Chapter 1 Configuring Interfaces and Circuits

Configuring the Switched Port Analyzer Feature

Note If the combined traffic bandwidth of the ingress and egress traffic of the SSPAN port exceeds the bandwidth of the DSPAN port, the DSPAN port may become oversubscribed.

•copyTxOnly - CSS copies to the DSPAN port only those packets that the SSPAN port transmits to the network (egress traffic).

•copyRxOnly - CSS copies to the DSPAN port only those packets that the SSPAN port receives from the network (ingress traffic).

For example, to copy all received and transmitted packets on SSPAN port 3 of the I/O module in slot 3 to DSPAN port 12 on the same module, enter:

(config)# setspan src_port 3/3 dest_port 3/12 copyBoth

To return the SPAN feature to its default state of disabled, use the no setspan command. For example, to disable SPAN on the source and destination ports on CSS module 3 in the example above, enter:

(config)# no setspan src_port 3/3 dest_port 3/12

Verifying the SPAN Configuration on a CSS

To verify the SPAN configuration on a CSS, use the show setspan command.

Table 1-15describes the fields in the show setspan command output.
