Cisco 6509 Switches

The throughput on the Cisco switch is different for fiber and copper ports. The fiber ports are fabric enabled. This means that they hand off frames to one another with a throughput of 256 Gb/s. This is the equivalent of 64 GigE cards continuously transmitting and receiving at their theoretical limits with no overhead. This section describes the following tasks:

Configure a single port
Show a single link
Create an LACP link aggregation
Create a PAgP link aggregation




	NOTE: The information in this section pertains to Cisco IOS Version 12.2.

Configuring a Single Port

Router1#config term
config command 1
.
.
Ctrl+Z
Switch1#interface gigabitethernet 9/5
Switch1(config-if)#switchport
Switch1(config-if)#no shutdown
Switch1(config-if)#end

1	Enter configuration commands, one per line. End with Ctrl+Z or `end`.

Showing a Single Port

Router1#show interface gigabitethernet 7/1
GigabitEthernet7/1 is up, line protocol is up (connected)
  Hardware is C6k 1000Mb 802.3, address is 0001.63d1.6016 (bia 0001.63d1.6016)
  MTU 9000 bytes, BW 1000000 Kbit, DLY 10 usec, 
     reliability 255/255, txload 1/255, rxload 1/255

Creating an LACP Link Aggregation

Switch1#enable
Password:password
Switch1#config term
config command 1
.
.
Ctrl+Z
Switch1(config-if)#interface range gigabitethernet 3/1 - 3
Switch1(config-if-range)#no ip address
Switch1(config-if-range)#channel-protocol lacp
Switch1(config-if-range)#channel-group 1 mode active

Creating a port-channel interface Port-channel 1
Switch1(config-if-range)#end
Switch1#config term
config command
.
.
Ctrl+Z
Switch1(config)#interface port-channel 1
Switch1(config-if)#no shutdown
Switch1(config-if)#end

1	Enter configuration commands, one per line. End with Ctrl+Z or `end`.

Creating an PAgP Link Aggregation

Switch1#enable
Password:password
Switch1#config term
config command 1
.
.
Ctrl+Z
Switch1(config-if)#interface range gigabitethernet 7/1 - 4
Switch1(config-if-range)#no ip address
Switch1(config-if-range)#channel-protocol pagp
Switch1(config-if-range)#channel-group 7 mode desirable

Creating a port-channel interface Port-channel 7
Switch1(config-if-range)#end
Switch1#config term
config command
.
.
Ctrl+Z
Switch1(config)#interface port-channel 7
Switch1(config-if)#no shutdown
Switch1(config-if)#end

1	Enter configuration commands, one per line. End with Ctrl+Z or `end`.

Displaying the Link Aggregation
