LINK AGGREGATION INTEROPERABILITY OF THE DELL POWERCONNECT 6200 SERIES SWITCH

CONFIGURING A CISCO IOS SWITCH FOR STATIC LINK AGGREGATION

The following example shows the Cisco IOS CLI commands for configuring three ports of the

Cisco switch for static link aggregation.

3750(config)# interface range GigabitEthernet 1/0/9 - 11

3750(config-if)# channel-group 1 mode on

COMMAND DESCRIPTION

set channelprotocol lacp 2

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).

port lacp-channel 2/9-11 mode on

Configures the three Ethernet ports (2/9, 2/10, and 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.

CONFIGURING A CISCO CATOS SWITCH FOR STATIC LINK AGGREGATION

The 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 2/9-11 mode on

COMMAND DESCRIPTION

interface range GigabitEthernet 1/0/9 - 11

Sets the CLI mode to configure three Gigabit Ethernet ports

(1/0/9, 1/0/10, and 1/0/11).

channel-group 1 mode on

Aggregates the three ports into a static LAG. Static LAGs do

not use LACP and are defined in the Cisco CLI by setting the

channel-group mode to ‘on’. The ‘1’ for the channel-group

number only has meaning within the switch and is used to

differentiate channel-groups. The number of channel-groups

supported by Cisco switches depends on the switch model.

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 2/9-11 mode on
