Egress Queuing Limitations
The Cisco NCS 520 Router supports tail drop queuing on egress interfaces using the queue-limit command. The following limitations apply to egress queuing:
-
Egress QOS can be applied to a total of 82 EFPs at a system level.
-
If you configure a queue size that the router cannot achieve within 1% accuracy, the configuration is rejected. The command output presents recommendations for the closest possible lower and higher configuration value.
-
Egress policy-map with queuing action is not supported on port-channel interface(LAG). The policy must be applied to the policy-maps on the member links.
-
The maximum bytes value of the queue-limit number-of-packets [bytes | ms | packets] command is 200 KB.
-
The show policy-map interface command displays the default queue-limit.
-
The queue-limit percent command is supported.
