August 2005 Page 10 Dell Enterprise Product Group Cisco CatOS CLI allows th e configuration of static LAGs via the LACP or the PAgP CLI commands. Both commands are shown below. The following example shows the Cisco CatOS C LI LACP channelprotocol commands for configuring three ports o f the Cisco sw itch for st atic link aggr egation.

August 2005 Page 12 Dell Enterprise Product Group NOTE: This is different from the Cisco IOS and Ca tOS methods which would require that all the ports in the LAG be configured to 100 Mbps an d full duplex rather than setting the LAG to 100Mbps.
August 2005 Page 13 Dell Enterprise Product Group CLI will prevent adding internal ports to a LAG To check the configuration of the ports on the Dell PowerConnect 5316 M use the ‘show running- config’ command and look at the “interface Ethernet gxx” configurations, where the “xx” indicates the port number.
August 2005 Page 14 Dell Enterprise Product Group Cisco IOS based switches may h ave the ‘desirable’ and ‘passive’ mode options for the LAG setting. The PowerConnect 5316M does not support this im plementation. Do not use the ‘desirable’ or ‘passive’ modes when configurin g a LAG with a De ll PowerConnect swit ch.
