HP ProCurve Switch 4000M / 8000M / 2424M / 1600M Reviewer’s Guide

traffic flow analysis for network planning and for top-down network troubleshooting. Problems can

quickly be identified so that segment-specific troubleshooting can be performed with a network

analyzer.

2.15.4 Network Monitoring Port

If more RMON groups (such as packet capture) are desired, a RMON probe can be attached to one of

the HP ProCurve Switch 4000M/8000M/2424M/1600M ports and a Network Monitoring Port can be

configured into the switch. A Network Monitoring Port allows the end user to copy all traffic from a

number of ports to a single destination port. (The source ports can be designated by specifically

naming the ports, or on a VLAN basis.) This allows the probe to see all traffic on the selected ports to

provide the probe with the proper global perspective.

LAN analyzers can also use this feature when doing specific monitoring or troubleshooting of network

segments.

2.15.5 Console Support

Out-of-band management of HP switches can be done through the RS-232 console port either via a

directly connected terminal emulator or over a modem connection. The console interface provides full

screen access to all configuration parameters. Context sensitive help is available for specific

configuration parameters. Full page help screens can be accessed to explain concepts or provide

overviews of an entire configuration screen.

The 4000M/8000M/2424M/1600M also provide an extensive event log to rapidly establish detailed switch

status and allow rapid troubleshooting of problems. Events from this log can be sent to a SNMP

management station as traps. The entire event log can also be sent to a PC or workstation through

TFTP.

The console interface is also available in-band through the telnet service.

For ease of use, the HP ProCurve Switch 4000M/8000M/2424M/1600M can search for particular values

through the console interface. For example, a search for a particular MAC address anywhere in the

configuration can be done saving the operator’s time when changing a configuration or reviewing the

address forwarding table.
