unique and not already defined.
3
source { interface | range } direction
{rx | tx | both} Specify the source port or range of ports. Specify the

6
no disable Enter the no disable command to enable the ERPM
session.
The following example shows an ERPM configuration:
Dell(conf)#monitor session 0 type erpm
Dell(conf-mon-sess-0)#source gigabitethernet 1/9 direction rx
Dell(conf-mon-sess-0)#source port-channel 1 direction tx
Dell(conf-mon-sess-0)#erpm source-ip 1.1.1.1 dest-ip 7.1.1.2 gre-protocol 111
Dell(conf-mon-sess-0)#no disable
Dell(conf)#monitor session 1 type erpm
Dell(conf-mon-sess-1)#source vlan 11 direction rx
Dell(conf-mon-sess-1)#erpm source-ip 5.1.1.1 dest-ip 3.1.1.2 gre-protocol 139
Dell(conf-mon-sess-1)#flow-based enable
Dell(conf-mon-sess-1)#no disable

The next example shows the configuration of an ERPM session in which VLAN 11 is monitored as the source interface and a MAC ACL
filters the monitored ingress traffic.
Dell(conf)#mac access-list standard flow
