Displaying QoS Profile Information on the BlackDiamond 10K Switch Only
To display QoS information on the BlackDiamond 10K switch, use the following command:
show qosprofile {ingress | egress} {ports [ all | <port_list>]}
Displayed information includes:
●
QoS profile name
●
Minimum bandwidth
●
Maximum bandwidth
●
Priority
Guidelines for Configuring QoS
The following are useful guidelines for configuring QoS:
●
If you are using DiffServ for QoS parameters, Extreme Networks recommends that you also
configure 802.1p or port-based QoS parameters to ensure that high-priority traffic is not dropped
prior to reaching the Master Switch Module (MSM).
●
The command to replace the 802.1p or DiffServ value affects only those traffic groupings based on
explicit packet class of service and physical/logical groupings.
Egress Traffic Rate Limiting—Aspen 8810 Switch Only
You can configure the maximum egress traffic allowed per port by specifying the committed rate, or
you can allow the egress traffic to pass an unlimited flow.
You can limit egress traffic on a 1 Gbps port in increments of 64 Kbps; on a 10 Gbps port, you can limit
egress traffic in increments of 1 Mbps. Optionally, you can also configure a maximum burst size, which
is higher than the limit, allowed to egress the specified port(s) for a burst, or short duration.
The default behavior is to have no limit on the egress traffic per port.
To view the configured egress port rate-limiting behavior, issue the following command:
show ports {<port_list>} information {detail}
You must use the
detail
parameter to display the Egress Port Rate configuration and, if configured, the
Max Burst size. Refer to “Displaying Port Configuration Information” for more information on the
show
ports information
command.
You can also display this information using the following command:
show configuration vlan
