Configuring Your ELS10-26

Perturbed — Trunking is enabled, and a good trunk connection has been established. However, the forwarding of data packets is temporarily suspended to allow for a change in the membership of the Trunk Group.

3.8 ENABLING PORT MONITORING

The ELS10-26 allows you to monitor the 10BASE-T ports on the ELS10-26 (you cannot monitor the 100BASE ports ). The monitoring of network traffic is performed by the ELS10-26 hardware, and the monitor image reflects the original packet. The ELS10-26 monitoring function maintains the original packet ordering of bridging frames between the inbound and outbound interfaces.

Using the LCM or a NMS, you can monitor a port, and select to monitor only packets received, only packets transmitted, or packets both received and transmitted by a port (if the port is operating in half duplex). In full duplex you can mirror either recieved packet or transmitted packet (not both).

To enable port monitoring on the ELS10-26:

1.Connect a network analyzer to the port labeled MONX on the ELS10-26.

2.Using the LCM or NMS, select the port or range of ports you want to monitor. Also select to monitor the received packets (Rx) or transmitted packets (Tx). If you do not select either the transmit or recieve options, the ELS10-26 will monitor both types of packets.

For example, mirror 2 Tx

This will turn on monitoring for packets transmitted on port 2.
