This illustrates three possible port channel configurations: Port channel A aggregates two links on According to cisco transmit discards / output discards typically refer to network congestion -- but in my experience they're often caused by faulty hardware. Cisco MDS 9396V Hi, I have two Cisco 9509 mds switches, switch 1 and switch 2 interconnect via TE ports from each of the VSANs VSAN 1 and VSAN 2. One of two dark fibers was disconnected due to some maintenance in the field/street by the provider. When you downgrade from Cisco MDS NX-OS Release 9. 5(1), the limit ranges from 0. This MIB manages PortChannel ports in the Cisco MDS 9000 Family. Cisco MDS SAN-OS Release 2.
