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.
