CLI will prevent adding internal ports to a LAG
To check the configuration of the ports on the Dell PowerConnect 5316M use the ‘show running-
config’ command and look at the “interface Ethernet gxx” configurations, where the “xx” indicates
the port number. In the following example, the “no gvrp enable” command would have to be
issued on port g11 before it could be added to a LAG.
5316M(config-if)# exit
5316M(config)# exit
5316M# show running-config
interface range ethernet g(13-16)
channel-group 1 mode on
exit
interface ethernet g11
gvrp enable
exit
Port configuration differences with Dell and CISCO
On the Dell PowerConnect 5316M, configurations for the LAG take precedence over the
configuration of the port. In the following example, port g11 is actually set to 100 Mbps (and not
set at 10 Mbps) because the LAG is set to 100 Mbps. If g11 is removed from the LAG, the port
configuration will be applied (g11 would be set to 10Mbps)
5316M# show running-config
interface port-channel 1
speed 100
no negotiation
exit
interface ethernet g11
speed 10
no negotiation
exit
interface range ethernet g(11,13-16)
channel-group 1 mode on
exit
On Cisco IOS and CatOS based switches, ports must be configured identically to be included in a
LAG.
