HP 11900 Switch Series - HP 11900-CMW710-R2105 Release Notes

 Workaround: Make sure the switches have similar card configurations, can back up each other,

and are rebooted at the same time. If the IRF fabric splits, reboot the smallest IRF system so the

switches can join the system to re-form a 4-chassis fabric.

 Symptom: After an incompatible ISSU on an IRF fabric that is the root of the TRILL multicast

distribution tree, the TRILL nickname (bridge MAC address) of the IRF fabric is changed but the root

name is not changed to the new name, resulting in a 20 -minute interruption of multicast traffic.

 Condition: This symptom occurs after an incompatible ISSU on an IRF fabric that is the root of the

TRILL multicast distribution tree. After the ISSU, the TRILL nickname (bridge MAC address) of the IRF

fabric is changed, but the root name of the TRILL multicast distribution tree is not changed to the new

name.

 Workaround: Before you perform the incompatible ISSU, reduce the root priority for the IRF fabric

to let it become a non-root RB. After the ISSU, increase the root priority for the IRF fabric to become

the root.
