Opened: Mar 10, 2021

Severity: 3-Major

Symptoms

Significant increase in CPU usage post-upgrade.

Impact

Significant increase in CPU usage, leading to potential degradation or disruption of traffic.

Conditions

- Upgrading from version 13.x to a later version. - Configured BIG-IP Virtual Edition (VE) that uses the sock driver.

Workaround

Create the following overrides: - In '/config/tmm_init.tcl' add or append the following: ndal mtu 1500 1137:0043 device driver vendor_dev 1137:0043 xnet - In '/config/xnet_init.tcl' add or append the following: device driver vendor_dev 1137:0043 dpdk Note: These overrides must be re-applied every time an upgrade is done.

Fix Information

Changed configuration to use DPDK-XNet as the default driver for Cisco eNIC.

Behavior Change

TMM now uses XNet and DPDK drivers as the default when operating with Cisco eNIC cards.
