Output Discards Cisco Nexus 9000

Output Discards Cisco Nexus 9000. On the client, the * is beside 172.16.1.10, which is configured as the preferred ntp server in the configuration. Output discards part of show interface command does not display real packet drops due to queuing/buffer drops for ports on tors with gem cards (northstar or donner based).

Products (2) cisco nexus 3000 series switches, ciscopro workgroup etherswitch software. Output discard incrementing on l2 ports. Input discards due to eth1/9 exceeding line rate.

The Updated Graph More Accurately Displays The True I/O Rate Of The Interface.

See the cisco nexus 3548 active buffer monitoring whitepaper and the section in this document for further information about this feature. Input discards while an access/trunk port transitions into stp forwarding state step 6.

Another Potential Indication Would Be Output Discards.

Image 13 shows the updated i/o graph for an interface that experienced output drops. Output discard incrementing on l2 ports. That is generally from the port queue's filling up and tail dropping because it cannot transmit the data fast enough.

Pause frames received on the egress interface do not prevent the output discards. And multiple interfaces may slowly increment output discards, even with little to no egress. If the output discards actively increment, enable active buffer monitoring (abm) with this command.

Note that the command allows you to monitor unicast or multicast, but not both. Products (2) cisco nexus 3000 series switches, ciscopro workgroup etherswitch software. An egress fcoe interface logs output discards during congestion even though pause frames are sent upstream on the ingress interface.

All interfaces where discards occur are fex ports. Output discards part of show interface command does not display real packet drops due to queuing/buffer drops for ports on tors with gem cards (northstar or donner based). Cisco nexus 9000 series switches.
