conguration mode. The session number needs to be
unique and not already dened.
3
source {interface | range } direction
{rx | tx | both}
Specify the source port or range of ports. Specify the
ingress (rx), egress (tx), or both ingress and egress

statements in an ERPM monitoring session.
4
erpm source-ip-address dest-ip-address
gre-protocol <value>
Specify the source IP address, destination IP address,
and the gre–protocol type value to which encapsulated
mirrored trac is sent.
5
flow-based enable
Specify ERPM to be performed on a ow-by-ow basis
or if you congure a VLAN source interface. Enter no
flow-based disable to disable ow-based ERPM.
6
no disable
Enter the no disable command to activate the
ERPM session.
The following example shows a sample ERPM conguration.
Dell(conf)#monitor session 0 type erpm
Dell(conf-mon-sess-0)#source tengigabitethernet 0/9 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 conguration of an ERPM session in which VLAN 11 is monitored as the source interface and a MAC ACL
lters the monitored ingress trac.
Dell(conf)#mac access-list standard flow
