Cisco CatOS CLI allows the configuration of static LAGs via the LACP or the PAgP CLI commands.
Both commands are shown below.
The following example shows the Cisco CatOS CLI LACP
channelprotocol
commands for
configuring three ports of the Cisco switch for static link aggregation.
Cat_6509(enable) set channelprotocol lacp 2
Cat_6509(enable) set port lacp-channel 2/1-6 mode on
The first command sets module 2 to use the LACP commands to configure LAGs. Since we are
defining a static LAG, the setting for the ‘channelprotocol’ does not matter (more on this below).
The second command configures the three Ethernet ports (
2/9 through 2/11) into a static LAG.
Static LAGs do not use LACP and are defined in the Cisco CLI by setting the lacp-channel mode to
‘
on’.
The following example shows the Cisco CatOS CLI PAgP
channelprotocol
commands for
configuring three ports of the Cisco switch for static link aggregation using the PAgP command.
Cat_6509(enable) set channelprotocol pagp 2
Cat_6509(enable) set port channel 2/1-6 mode on
The first command sets module 2 to use the PaGP commands to configure LAGs. As we mentioned
before, since we are defining a static LAG, the setting for the
‘channelprotocol’
does not
matter. The second command configures the three Ethernet ports (
2/9 through 2/11) into a
static LAG. Static LAGs do not use PAgP and are defined in the Cisco CLI by setting the
channel
mode
to
‘on’
.
The number of channel-groups supported by Cisco switches depends on the switch model.
Confirming a successful Static Link Aggregation
connection
Since LACP is not being used, only careful inspection of the Cisco and PowerConnect 5316M
configurations can confirm that a static LAG has been established. The following steps may be
helpful:
o Check cabling is to correct ports on both switches
o Check that all LAG ports have link
o Confirm via the Dell and Cisco switches’ “show running-config” commands, that the desired
ports are in the LAG
