Page 18: Port Mirroring
"General diagnostic tools " (page 22) Port mirroring Ethernet Routing Switch 8300 switches have a port mirroring feature that helps you to monitor and analyze network trafﬁc. The port mirroring feature supports both ingress (incoming trafﬁc) and egress (outgoing trafﬁc) port mirroring.
Page 19 Monitoring the MAC table helps you to understand how resources are being used and how close you are to approaching the C-MAC limit per R module lane. Nortel recommends that you enable port mirroring only for diagnostic purposes because this feature degrades switch performance. Copyright © 2007, Nortel Networks...
Page 20: Port Statistics
20 Troubleshooting fundamentals You can use Device Manager, the Nortel Command Line Interface (NNCLI), or the Command Line Interface (CLI) to conﬁgure port mirroring. Port statistics The port statistics commands allow you to display information on received and transmitted packets at the ports. The ingress and egress counts are taken at the MAC layer.

This section describes the Nortel Networks Command Line Interface (NNCLI) command modes you use to conﬁgure the Ethernet Routing Switch 8300 and the commands you use to access the NNCLI. You can access the NNCLI using the following methods: •...
Page 24 • Global conﬁguration mode You can use this mode to make changes to the running conﬁguration. If you save the conﬁguration, these settings survive reboots of the switch. • Interface conﬁguration mode You can use this mode to modify either a logical interface, such as a VLAN, or a physical interface, such as a port/slot.

Page 33: Using System Logging
Using system logging By default, a system log (syslog) ﬁle is created when a PCMCIA card is present in the switch. All log entries are saved to this ﬁle including encrypted crash dump information. The log ﬁle is named according to 8.3 format (xxxxxxxx.sss).
Page 34: Transferring A Log File To A Remote Machine
You can conﬁgure up to 10 hosts and they are tried in the order conﬁgured. After a ﬁle reaches its maxsize, the switch attempts to copy the syslog to the server/host conﬁgured. If there are no hosts conﬁgured or the hosts are unreachable the switch stops logging to the syslog and all new entries are logged in DRAM.
