Effect on outbound bandwidth allocation
6 10% Queue 6 has a GMB of 10% and, if oversubscribed, is subordinate
to queues 8 and 7 in priority for any unused outbound bandwidth
available on the port.
5 10% Queue 5 has a GMB of 10% and, if oversubscribed, is subordinate
to queues 8, 7, and 6 for any unused outbound bandwidth
available on the port.
4 10% Queue 4 has a GMB of 10% and, if oversubscribed, is subordinate
to queues, 8, 7, 6, and 5 for any unused outbound bandwidth
available on the port.
3 30% Queue 3 has a GMB of 30% and, if oversubscribed, is subordinate
to queues, 8, 7, 6, 5, and 4 for any unused outbound bandwidth
available on the port.
2 3% Queue 2 has a GMB of 3% and, if oversubscribed, is subordinate
to queues, 8, 7, 6, 5, 4, and 3 for any unused outbound bandwidth
available on the port.
1 2% Queue 1 has a GMB of 2% and, if oversubscribed, is subordinate
to all the other queues for any unused outbound bandwidth
available on the port.
Either of the following commands configures ports 1 through 5 with bandwidth settings:
Switch(config) # int 1-5 bandwidth-min output 2 3 30 10 10 10 15 strict
Switch(interface 1–5) # bandwidth-min output 2 3 30 10 10 10 15 strict
Viewing the current GMB configuration
This command displays the per-port GMB configuration in the running-config file.
Syntax:
show bandwidth output <port-list|trk_#>
Without <port-list|trk_#> , this command lists the GMB configuration for all ports and static trunks on the
switch.
With <port-list|trk_#> , this command lists the GMB configuration for the specified ports and static trunks.
This command operates the same way in any CLI context. If the command lists Disabled for a port or trunk,
there are no bandwidth minimums configured for any queue on the port or trunk. (See the description of the no
form of the bandwidth-min output command.)
Listing the GMB configuration on page 169 displays the GMB configuration resulting from either of the above
commands.
Listing the GMB configuration
switch(config)# show bandwidth output 1-5, trk1
