OmniSwitch 6600/7000/8800—Release 5.1.5.R04 page 79

VRRP neighbors may switch between master and backup when more than 20 virtual routers are on the
OS7000.
Workaround: One must have OS7-GNI-U2’s with a 1.3 Catalina or greater. The version of the Catalina
for a Gigabit module is determined by running the command "show ni <slot>". In the line "ASIC-Physi-
cal", the last two values represent the version of the Catalina i.e.
ASIC - Physical: 0x1901 0x0201 0x0201
The version number should be greater than 0x0301

VRRP will occasionally send out the hardware MAC instead of the virtual MAC
Workaround: Make sure clients on the network honor gratuitous ARP's. If this is not possible, use an IP
address that is not actually assigned to an interface as the VRRP IP address. This will ensure that no hard-
ware MAC address is ever associated with the virtual IP address.

On the OS7000, this debug message may be seen when VRRP is enabled. Please ignore as it does not
affect functionality.
Workaround: There is no known workaround at this time.
