Cisco Catalyst 3750 and 2970 Switches: Using Switches with a PS Series Group

Note: You can use the

spanning-tree portfast default global configuration command to

globally enable the PortFast feature on all nontrunking ports.

This example shows how to globally enable PortFast by default on all access ports:

Switch# config t

Switch(config)# spanning-tree portfast default

Switch(config)# end

Switch# copy running-config startup-config

See the Cisco Catalyst 3750 Switch Software Configuration Guide or the Cisco Catalyst 2970

Switch Software Configuration Guide for information on configuring Spanning-Tree Protocol.

For additional information on understanding and configuring Spanning-Tree Protocol on Catalyst

switches, see:

Configuring Flow Control

This section describes how to configure Flow Control on Cisco Catalyst 3750 and 2970switches.

You must enable Flow Control on each switch port that handles iSCSI traffic.

Note: Cisco Catalyst 3750 and 2970 switch ports are capable of receiving, but not sending, pause

frames.

The following commands shows how to configure Gigabit Ethernet interface 0/1 on switch 1 to

auto-negotiate the correct Flow Control setting with the device to which it is connected:

Switch> enable

Switch# configure terminal

Switch(config)# interface gigabitethernet1/0/1

Switch(config-if)# flowcontrol receive desired

Switch(config-if)# exit

Switch(config)# exit

Switch# copy running-config startup-config

To view or confirm Flow Control status on a port, use the following command:

Switch# show flowcontrol interface gigabitethernet1/0/1

See the Cisco Catalyst 3750 Switch Software Configuration Guide or the Cisco Catalyst 2970

Switch Software Configuration Guide for detailed information on configuring Flow Control.
