OmniSwitch 6600/7000/8800—Release 5.1.5.R04 page 57
PR 81736
On OS8800 switches, when more linkagg ports with same configuration than the size of the linkagg, when
any of active port goes down the non-joining ports do not join the aggregate.
Workaround: Do not configure more ports than the actual linkagg size.
PR 81937
With optimization enabled command, its impossible to delete a port from linkagg.
Workaround: Disable optimization command to delete the ports from linkagg. and re-enable the optimi-
zation command.
PR 81985
On the OS8800, LACP ports do not join the aggregate if some of the ports are administratively down.
Workaround: If the ports needs to administratively down and if they are part of LACP linkagg, remove
the ports from LACP and add them again when they admin up.
PR 84225
On an OS7000, multiple linkagg on the same VLAN should be on the same flooding mode if optimization
is enabled, to pass bridging traffic between them.
Workaround: Do not create mixed mode linkagg ports in the same Slice.
PR 84437
On OS8800 first-generation NI modules, there could be mac movement across the link aggregation ports
and the user ports.
Workaround: Enable the optimzation mode on link aggregation modules.
Port Mirroring
Feature Exceptions
• On OS6600 switches, Port Mirroring is not supported across a stack, i.e. mirrored port on slot 1 and
mirroring port on slot 4.
• On an OS6648, port mirroring is not supported between lower ports (Fast Ethernet port 1-24 or Giga-
bit Ethernet port 51-52) and upper port (Fast Ethernet port 25-48 or Gigabit Ethernet port 49-50).
• On an OS6602-48, port mirroring is not supported between lower ports (Fast Ethernet port 1-24 or
Gigabit Ethernet port 51-52) and upper port (Fast Ethernet port 25-48).
• When port mirroring is enabled on OS7000/8800 Gigabit modules, Egress mirror performance is
1330974 p/s.
• When port mirroring is enabled on an OS8-GNI-C24, Egress mirror performance is 1430792 p/s.
