LINK AGGREGATION INTEROPERABILITY OF THE DELL POWERCONNECT 6200 SERIES SWITCH

CONFIRMING A SUCCESSFUL DYNAMIC LINK AGGREGATION

CONNECTION WITH CISCO IOS

The following example shows how the Cisco IOS show interfaces port-channel 1

etherchannel command can be used to assure that the Cisco has established a LAG and

that the LAG is connected.

3750# show interfaces port-channel 1 etherchannel

Port-channel1 (Primary aggregator)

Age of the Port-channel = 00d:01h:11m:34s

Logical slot/port = 10/1 Number of ports = 4

HotStandBy port = null

Port state = Port-channel Ag-Inuse

Protocol = LACP

Ports in the Port-channel:

Index Load Port EC state No of bits

------+------+------+------------------+-----------

0 00 Gi1/0/1 Active 0

0 00 Gi1/0/2 Active 0

0 00 Gi1/0/3 Active 0

0 00 Gi1/0/4 Active 0

The output of the command shows the ports Gi1/0/1 through Gi1/0/4 are “Active.” This

confirms that there is physical link on all ports in the LAG and that the Cisco switch has

communicated with the PowerConnect 6200 Series switch to successfully establish an

aggregated link on ports 1/0/1 through 1/0/4 with LACP.

CONFIRMING A SUCCESSFUL DYNAMIC LINK AGGREGATION

CONNECTION WITH CISCO CATOS

The following example shows how the Cisco CatOS show interfaces lacp-channel

info

command can be used to assure that the Cisco switch has established a LAG and that

the LAG is connected.

Cat_6509> (enable) show lacp-channel info

Chan Port Status Channel Admin Speed Duplex Vlan

id mode group

---- ----- ---------- -------------------- ----- ----- ------ ----

801 2/1 connected active 395 a-1Gb a-full 1

801 2/2 connected active 395 a-1Gb a-full 1

801 2/3 connected active 395 a-1Gb a-full 1

801 2/4 connected active 395 a-1Gb a-full 1

. . .

The output of the command shows the status for ports 2/1 through 2/4 is “connected” and that

the channel mode is “active.” This confirms that there is physical link on all ports in the LAG

and that the Cisco switch has communicated with the PowerConnect 6200 Series switch to

successfully establish an aggregated link on ports 2/1 through 2/4 with LACP.
