Encapsulated Remote-Port Monitoring

Encapsulated Remote Port Monitoring (ERPM) copies traffic from source ports/port-channels or source

VLANs and forwards the traffic using routable GRE-encapsulated packets to the destination IP address

specified in the session.

When configuring ERPM, follow these guidelines:

The Dell Networking OS supports ERPM source sessions only. Encapsulated packets terminate at the

destination IP address or at the analyzer.

You can configure up to four ERPM source sessions on the switch.

You can configure any port as a source port in an ERPM session.

The maximum number of source ports that can be defined in a session is 128.

Make sure that the destination IP address is reachable via the configured IP route (static or dynamic)

The system MTU should be configured properly to accommodate the increased size of the ERPM

mirrored packet.

The system encapsulates the complete ingress or egress data under GRE header, IP header and

outer MAC header and sends it out at the next hop interface as pointed by the routing table.

The source IP address can be any port's ip address defined in the box but it should be unique and

should not be assigned to any other system in the network.

You must specify the keyword monitor in the ACL rules used on a source interface (as shown in one

of the examples following the configuration procedure).

ERPM sessions do not copy locally sourced remote-VLAN traffic from source trunk ports that carry

RPM VLANs. ERPM sessions do not copy locally sourced ERPM GRE-encapsulated traffic from

source ports.

A flow-based source VLAN can be monitored only for ingress traffic (not egress traffic).

You can configure the port extender as source either as a physical interface or as a VLAN, whose

memebers are PEX ports or as VP lAGg.

To configure an ERPM session:

configure terminal

monitor session id type erpm

Enter global configuration mode.

Specify a session ID and ERPM as the type

of monitoring session, and enter
