routing table.
Step 13
Switch(config-mon-erspan-src-dst)# exit
Exits ERSPAN monitor destination session configuration mode and
returns to ERSPAN monitor source session configuration mode.
Step 14
Switch(config-mon-erspan-src)# exit
Exits ERSPAN monitor source session configuration mode and
returns to privileged EXEC mode.
Step 15
Switch(config)# erspan {tos tos-value |
ttl ttl-value}
Configures type of service (ToS) and Time to Live (TTL) values for
