PAN-308564

Packets are dropped on SD-WAN interfaces if they require fragmentation for an interface but have the Don't Fragment (DF) bit set. This results in unexpected packet drops. This affects client to server sessions when using SD-WAN for NGFW.

Workaround: Allow fragmenting packets with DF bit set (debug dataplane set ip4-ignore-df yes).

PAN-307795

This issue is now resolved. See PAN-OS 11.1.13-h1 Addressed Issues.

On a standalone Panorama, the system incorrectly generates system logs indicating a lost connection to its peer even when High Availability is not configured. You can safely ignore these logs, as they do not affect operations.

PAN-306502

This issue is now resolved. See PAN-OS 11.1.13 Addressed Issues.

TLS sessions using version 1.2 or earlier may fail when session traffic matches a decryption policy rule with the no-decrypt action under either of the following conditions:

If both of these conditions are met, the session is guaranteed to fail.

• Both HTTP header insertion (Objects > Security Profiles > URL Filtering > HTTP Header Insertion) and SSL/TLS handshake inspection (Device > Setup > Session > Decryption Settings > SSL Decryption Settings) are enabled.
• Log Successful SSL Handshake is not enabled in the decryption policy rule and neither Block sessions with expired certificates nor Block sessions with untrusted issuers is enabled in the attached decryption profile.

Workaround: Perform one of the following tasks:

• Enable Log Successful SSL Handshake in all no-decrypt decryption policy rules.
• Enable either Block sessions with expired certificates or Block sessions with untrusted issuers in the decryption profiles attached to the no-decrypt decryption policy rules.

PAN-305301

This issue is now resolved. See PAN-OS 11.1.13-h1 Addressed Issues.

The timing of GlobalProtect lifetime expiry or inactivity logout notifications used for GlobalProtect SSL tunnels may cause the pan_task process to stop responding and the dataplane to restart.

Workaround: Select Network > GlobalProtect > Gateways > > Agent > > Connection Settings and change the value of both Notify Before Lifetime Expires (min) and Notify Before Inactivity Logout (min) to 0.

PAN-304756

This issue is now resolved. See PAN-OS 11.1.13-h1 Addressed Issues.

After you disable the shared optimization feature in Panorama, ensure that you perform a full configuration push to all managed multi-vsys devices to re-establish a baseline. Failure to include every device group associated with the multi-vsys device during this push might result in incomplete or inconsistent configurations across virtual systems.

PAN-304576

Traffic interruption may occur when inspection of HTTP/2 traffic is enabled.

Workaround: Disable HTTP/2 server push using the set deviceconfig setting http2 server-push no CLI command.

PAN-303959

Traffic that is incorrectly identified as unknown-tcp/unknown-udp eventually drops due to an App-ID resource limitation issue.

PAN-303051

This issue is now resolved. See PAN-OS 11.1.13 Addressed Issues

The reportd process experiences a memory leak because it retains memory that was temporarily used for report generation. Once a task is complete, the process fails to release this memory for reuse, leading to continuous accumulation and eventual memory exhaustion on the Panorama device.

PAN-297295

VM-Series firewalls on Microsoft Azure environments only

After upgrading to an affected release, the firewall restarts continuously because the brdagent process restarts multiple times and exhausts its restart limit, resulting in a segfault error. This issue occurs when a high burst of traffic is sent to the Azure PA-VM (Palo Alto Networks Virtual Machine), and impacts production environments due to the regular reboots.

Workaround: Migrate the VM instance to Dv5 instance type. On these instance types, SYN packets are not routed to the synthetic path, avoiding this condition. Suggested direct resizing paths are:

• D3_v2/DS3_v2 to D8ds_v5
• D4_v2/DS4_v2 to D8ds_v5
• D5_v2/DS5_v2 to D16ds_v5

Azure VMs with ephemeral storage can only be resized to another type with ephemeral storage.

PAN-292202

The system logs repeatedly displayed the alert Clearing snmpd.log due to log overflow due to the SNMP counters rolling over. This is a benign message and does not impact device functionality.

PAN-289432

Generating a certificate with the block-private-key yes command on Panorama fails with the error:

Could not get parameters for double encryption. This occurred when the certificate was signed by an external Certificate Authority (CA).

PAN-289383

PA-800 series firewalls only

Upgrading firewalls to PAN-OS 11.0 or later causes SFP ports to go non-operational when the firewall uses forced port mode and the connected peer device operates without auto-negotiation.

Workaround: Enable auto-negotiation on the connected peer firewall.

PAN-286848

ECMP incorrectly balances sessions across links based on the configured metric, which leads to an imbalance in traffic distribution and results in traffic assignment shifting disproportionately to routes with lower metrics.

PAN-286496

NGFW Clusters

URL-continue and override continue selections will function like a general URL-block action.

PAN-285894

If the Preserve Pre-NAT feature is enabled, dataplane crashes may occur, which could result in firewall reboots.

Workaround: Disable the Preserve Pre-NAT feature using the set deviceconfig setting preserve-prenat-feature no CLI command.

PAN-283429

When you use custom certificates for the connection between Panorama and a log collector, the automated renewal for the predefined ElasticSearch certificates gets disrupted.

Workaround: Remove the custom certificates before the ElasticSearch certificates expire. This allows the system to correctly identify and renew the predefined ElasticSearch certificates. After the renewal is complete, re-install the custom certificates.

PAN-279415

Service routes configured for a data plane interface might incorrectly route traffic through the management plane interface instead. This issue impacts Syslog and CRL status traffic when the service route lacks a specific destination custom service route.

PAN-276920

URL filtering response pages may load slowly or fail to display when users request websites that are blocked in the URL Filtering profile (site access for the corresponding URL category is block, continue, or override) attached to the matching Security policy rule. This occurs on an intermittent basis.

PAN-275047

VM-Series firewalls only

After an upgrade, the firewall is unable to send logs to the Strata Logging Service (SLS) when using a specific proxy server, and the SSL connection status displays as failed when attempting to forward logs through the web proxy.

PAN-262556

The ElasticSearch cluster health status might continue to remain yellow for an extended period after upgrading to PAN-OS 11.1

PAN-260851

From the NGFW or Panorama CLI, you can override the existing application tag even if Disable Override is enabled for the application (Objects > Applications) tag.

PAN-254240

In the event of an HSCI flap on an NGFW cluster node, traffic reconvergence takes three to four seconds.

PAN-253963

The auto commit job may take longer than expected to complete when the Panorama management server is in Panorama or Log Collector mode.

PAN-251551

When an NGFW cluster agent crashes and doesn't recover, leader election will take approximately 45 seconds to begin and traffic failover will occur during that time.

PAN-250903

In a congestion scenario on an HSCI port of an NGFW cluster node, the QoS priorities of cross node traffic streams might be reversed if you're using the default QoS profile with class1 to class8 set as high to low.

PAN-247974

LACP flap is expected during a device failover in an NGFW cluster due to an L2 ctrld restart on the new leader node.

PAN-234015

The X-Forwarded-For (XFF) value is not displayed in traffic logs.

PAN-224502

The autocommit time of the VM-Series firewall running PAN-OS 11.1.0 might take longer than expected.

PAN-220180

Configured botnet reports (Monitor > Botnet) are not generated.

PAN-207733

When a DHCPv6 client is configured on HA Active/Passive firewalls, if the DHCPv6 server goes down, after the lease time expires, the DHCPv6 client should enter SOLICIT state on both the Active and Passive firewalls. Instead, the client is stuck in BOUND state with an IPv6 address having lease time 0 on the Passive firewall.

PAN-207611

When a DHCPv6 client is configured on HA Active/Passive firewalls, the Passive firewall sometimes crashes.

PAN-207442

For M-700 appliances in an active/passive high availability (Panorama > High Availability) configuration, the active-primary HA peer configuration sync to the secondary-passive HA peer may fail. When the config sync fails, the job Results is Successful (Tasks), however the sync status on the Dashboard displays as Out of Sync for both HA peers.

Workaround: Perform a local commit on the active-primary HA peer and then synchronize the HA configuration.

1. Log in to the Panorama web interface of the active-primary HA peer.
2. Select Commit and Commit to Panorama.
3. In the active-primary HA peer Dashboard, click Sync to Peer in the High Availability widget.

PAN-207040

If you disable Advanced Routing, remove logical routers, and downgrade from PAN-OS 11.0.0 to a PAN-OS 10.2.x or 10.1.x release, subsequent commits fail and SD-WAN devices on Panorama have no Virtual Router name.

PAN-206913

When a DHCPv6 client is configured on HA Active/Passive firewalls, releasing the IPv6 address from the client (using Release in the UI or using the request dhcp client ipv6 release all CLI command) releases the IPv6 address from the Active firewall, but not the Passive firewall.

PAN-206909

The Dedicated Log Collector is unable to reconnect to the Panorama management server if the configd process crashes. This results in the Dedicated Log Collector losing connectivity to Panorama despite the managed collector connection Status (Panorama > Managed Collector) displaying connected and the managed colletor Health status displaying as healthy.

This results in the local Panorama config and system logs not being forwarded to the Dedicated Log Collector. Firewall log forwarding to the disconnected Dedicated Log Collector is not impacted.

Workaround: Restart the mgmtsrvr process on the Dedicated Log Collector.

1. Log in to the Dedicated Log Collector CLI.
2. Confirm the Dedicated Log Collector is disconnected from Panorama. admin>``show panorama-status Verify the Connected status is no.
3. Restart the mgmtsrvr process. admin>``debug software restart process management-server

PAN-197588

The PAN-OS ACC (Application Command Center) does not display a widget detailing statistics and data associated with vulnerability exploits that have been detected using inline cloud analysis.

PAN-197419

PA-1400 Series firewalls only

In Network > Interface > Ethernet, the power over Ethernet (PoE) ports do not display a Tag value.

PAN-196758

On the Panorama management server, pushing a configuration change to firewalls leveraging SD-WAN erroneously show the auto-provisioned BGP configurations for SD-WAN as being edited or deleted despite no edits or deletions being made when you Preview Changes (Commit > Push to Devices > Edit Selections or Commit > Commit and Push > Edit Selections).

PAN-195968

PA-1400 Series firewalls only

When using the CLI to configure power over Ethernet (PoE) on a non-PoE port, the CLI prints an error depending on whether an interface type was selected on the non-PoE port or not. If an interface type, such as tap, Layer 2, or virtual wire, was selected before PoE was configured, the error message will not include the interface name (eg. ethernet1/4). If an interface type was not selected before PoE was configured, the error message will include the interface name.

PAN-194978

PA-1400 Series firewalls only

In Network > Interface > Ethernet, hovering the mouse over a power over Ethernet (PoE) Link State icon does not display link speed and link duplex details.

PAN-187685

On the Panorama management server, the Template Status displays no synchronization status (Panorama > Managed Devices > Summary) after a bootstrapped firewall is successfully added to Panorama.

Workaround: After the bootstrapped firewall is successfully added to Panorama, log in to the Panorama web interface and select Commit > Push to Devices.

PAN-187407

The configured Advanced Threat Prevention inline cloud analysis action for a given model might not be honored under the following condition: If the firewall is set to Hold client request for category lookupand the action set to Reset-Both and the URL cache has been cleared, the first request for inline cloud analysis will be bypassed.

PAN-186283

Templates appear out-of-sync on Panorama after successfully deploying the CFT stack using the Panorama plugin for AWS.

Workaround: Use Commit > Push to Devices to synchronize the templates.

PAN-184708

Panorama managed firewalls

Scheduled report emails (Monitor > PDF Reports > Email Scheduler) are not emailed if:

• A scheduled report email contains a Report Group (Monitor > PDF Reports > Report Group) which includes a SaaS Application Usage report.
• A scheduled report contains only a SaaS Application Usage Report.

Workaround: To receive a scheduled report email for all other PDF report types:

1. Select Monitor > PDF Reports > Report Groups and remove all SaaS Application Usage reports from all Report Groups.
2. Select Monitor > PDF Reports > Email Scheduler and edit the scheduled report email that contains only a SaaS Application Usage report. For the Recurrence, select Disable and click OK. Repeat this step for all scheduled report emails that contain only a SaaS Application Usage report.
3. Commit. () Select Commit > Commit and Push

PAN-184406

Using the CLI to add a RAID disk pair to an M-700 appliance causes the dmdb process to crash.

Workaround: Contact customer support to stop the dmdb process before adding a RAID disk pair to a M-700 appliance.

PAN-183404

Static IP addresses are not recognized when "and" operators are used with IP CIDR range.

PAN-181933

If you use multiple log forwarding cards (LFCs) on the PA-7000 series, all of the cards may not receive all of the updates and the mappings for the clients may become out of sync, which causes the firewall to not correctly populate the Source User column in the session logs.
