Symptoms

VLAN failsafe generates traffic using ICMP which fails if VLAN CMP hash is non-default.

Impact

There are very rare situations in which failsafe triggers but it should have not.

Conditions

VLAN failsafe configured on a non-default cmp-hash VLAN. When the VLAN failsafe situation occurs, and the generated arp requests are not being answered, VLAN failsafe resorts to ICMP.

Workaround

None.

Fix Information

VLAN failsafe no longer generates traffic using ICMP, and now supports non-default cmp-hash on VLAN.
