To configure an ERPM session:
Table 68. Configuration steps for ERPM
Step Command Purpose
1
configure terminal
Enter global configuration mode.
2
monitor session <id> type erpm
Specify a session ID and ERPM as the type of
monitoring session, and enter the Monitoring-Session
configuration mode. The session number needs to be
unique and not already defined.
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
traffic to be monitored. You can enter multiple source
statements in an ERPM monitoring session
4
erpm source-ip <id> dest-ip <id> gre-
protocol <value>
Specify the source IP address, destination IP address,
and GRE-protocol type value to which encapsulated
mirrored traffic is sent.
5
no flow-based enable
ERPM to be performed on a flow-by-flow basis or if
you configure a VLAN source interface. Enter the no
flow-based command to disable flow-based ERPM.
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 tengigabitethernet 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
Dell# show monitor session

1 Vl 11 remote-ip rx Flow 5.1.1.1 3.1.1.2 0 255 No 100 139
No Enabled
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
Dell(config-std-macl)#seq 5 permit 00:00:0a:00:00:0b count monitor
Dell#show running-config interface vlan 11
