Configuring Full PISA EtherChannel Bandwidth

A Supervisor Engine 32 PISA automatically creates an EtherChannel (port channel interface 256) that
the Supervisor Engine 32 and the PISA daughterboard use to communicate with each other. By default,
the PISA EtherChannel bandwidth is 1 Gbps. To increase the PISA EtherChannel bandwidth, you can
disable supervisor engine ports and reallocate the port ASIC capacity to the PISA EtherChannel.
To increase the PISA EtherChannel bandwidth, perform this task:
Command
Step 1
Router(config)# interface gigabitethernet slot/3
Or:
Router(config)# interface gigabitethernet
slot/[8 | 9]
Step 2
Router(config-if)# channel-group 256 mode on
Router(config-if)# no channel-group 256 mode on

Ports 1 through 8: Small form-factor pluggable (SFP) Gigabit Ethernet
Port 9: 10/100/1000 Mbps RJ-45 port
To avoid unexpected application of QoS to the
WS-S32-GE-PISA ports.
You can disable port 9 and reallocate its port ASIC capacity to the PISA EtherChannel (see the
"Configuring Full PISA EtherChannel Bandwidth" section on page 4-3
You cannot enter any configuration under port channel interface 256.
After the port becomes a member of the PISA EtherChannel, only the no channel-group 256 mode
on command has any effect on the port until the port is no longer a member of the PISA
EtherChannel. While the port is a member of the PISA EtherChannel, all port configuration
commands except the [no] channel-group 256 mode on command are ignored.
The PISA EtherChannel MTU size is 4,096 bytes.
