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-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-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-298505

This issue is now resolved. See PAN-OS 11.1.10-h7 Addressed Issues and PAN-OS 11.1.12 Addressed Issues

After upgrading multi-vsys firewalls, the sequence of the virtual system IDs (vsys ID) changes causing auto-commit failures with validation errors. This occurs when the multi-vsys firewall has virtual systems managed by Panorama, and the vsys ID sequence breaks when unused virtual systems are deleted and the changes are pushed to the firewall.

PAN-294179

This issue is now resolved. See PAN-OS 11.1.10-h4 Addressed Issues.

On thePanorama Config Audit page, some commit versions might display incorrect or missing data. Fields such as, COMMITTED BY, COMMIT DATE, andOBJECT CHANGES might not be visible for some commit versions. Sometimes, commit versions can disappear after a refresh and the commit description field might display corrupted characters.

PAN-293673

This issue is now resolved. See PAN-OS 11.1.11 Addressed Issues

When the firewall generates a high volume of logs and attempts to export these logs to an FTP server, it may consume excessive memory leading to all PAN-OS processes crashing.

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

PAN-290235

This issue is now resolved. See PAN-OS 11.1.11 Addressed Issues.

The dscd process crashes continuously on MIPS platforms (for example, PA-850 firewalls) due to a runtime error related to an invalid memory address or nil pointer dereference. This occurs when the golang library upgrade in CIE is not compatible with the MIPS platform.

PAN-290088

This issue is now resolved. See PAN-OS 11.1.11 Addressed Issues

When pushing configurations from Panorama to a firewall, a memory leak might occur in the firewall's configd process, particularly when the configurations contain shared policies. Each configuration push causes the configd process to consume additional memory that is not released after the commit completes.

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-287056

This issue is now resolved. See PAN-OS 11.1.10-h1 Addressed Issues

A BGP export policy rule that matches on a next hop fails to block the advertisement of static routes, and the firewall incorrectly matches the egress interface IP address instead of the original next-hop IP address of the static route, which causes the deny rule to fail.

PAN-286897

This issue is now resolved. See PAN-OS 11.1.10 Addressed Issues.

The pan_task process might fail when the firewall attempts to forward files to the WildFire public cloud, which can cause the dataplane to experience heartbeat failures.

Workaround: Disable the firewall WildFire Analysis profile.

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-286306

This issue is now resolved. See PAN-OS 11.1.10-h1 Addressed Issues

Workaround: Disable accumulation proxy on the NGFW.

PAN-286231

This issue is now resolved. See PAN-OS 11.1.11 Addressed Issues

When performing a partial Commit and Push on Panorama, there is a risk that unintended configuration changes might be pushed to a firewall.

This issue is more likely to occur in the following scenarios:

• When you run Commit and Push operations as a single action.
• When you trigger multiple parallel commit-all jobs at the same time.
• Device groups and templates have different configuration synchronization versions.

Workaround: Perform one of the following steps:

• Perform commit and push as two separate, sequential steps.
• Perform a full push instead of selective push.

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-283467

PA-3400 Series firewalls only

The firewall might unexpectedly reboot and enter maintenance mode due to a ctd-agent out-of-memory (OOM) condition when undergoing advanced services load testing with a high volume of IoT EAL log forwarding.

Workaround: Limit the number of EAL logs generated by the firewall using the following CLI command: debug iot eal key-value EAL_PENDING_BYTES=1000.

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-282854

This issue is now resolved. See PAN-OS 11.1.11 Addressed Issues

The Elasticsearch cluster fails to start after deploying dedicated log collectors in a multi-collector environment.

Workaround: Restart all the involved log collectors.

PAN-280532

This issue is now resolved. See PAN-OS 11.1.10 Addressed Issues.

When you use a single syslog server over TCP for log forwarding, and the connectivity to the syslog server breaks, syslog forwarding does not resume even after the connectivity to the server restores.

Workaround: Performing one of the following tasks:

• Reboot the firewall.
• Temporarily, configure syslog to use UDP, commit the configuration, revert to TCP, and then commit.

PAN-279901

When decryption is enabled, segmented Client Hello packets can cause website access issues and memory leaks under the following conditions:

• The segmented Client Hello packets arrive out-of-order
• The segmented Client Hello packets arrive out-of-order and can be reassembled into a complete Client Hello when the first contiguous segment is formed by NGFW
• The first segment of the Client Hello packets is less than 5 bytes
• A decryption policy rule excludes this traffic from decryption and a Security policy rule (URL filtering) denies this session

To enable this fix, run the CLI command bug dataplane set ssl-decrypt accumulate-client-hello disjoined yes

PAN-279621

This issue is now resolved. See PAN-OS 11.1.9 Addressed Issues.

Early aging and removal of firewall session while they are still active can lead to intermittent instabilities and crashes for proxy traffic, the Content and Threat detection engine, and any data-path processing.

PAN-279415

This issue is now resolved. See PAN-OS 11.1.11 Addressed Issues

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

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.
