Foundry Networks Switch and Router Installation And Configuration Manual page 221

NOTE: The SNMPv2c support does not include support of SNMPv2c traps. Also, IronView/UNIX does not
support SNMPv2c.
Remote Monitoring (RMON) Statistics
All Foundry devices include an RMON agent that supports the following groups. The group numbers come from
the RMON specification (RFC 1757).
• Statistics (RMON Group 1) – Current packet and error statistics for each port.
• History (RMON Group 2) – Samplings of packet and error statistics captured at regular intervals. You can
configure the sampling rate and the number of "buckets" in DRAM for storing the samplings.
• Alarms (RMON Group 3) – A list of alarm events, which indicate that a threshold level for a specific part of the
device has been exceeded. You can select the system elements you want RMON to monitor and the
thresholds for triggering the alarms.
• Events (RMON Group 9) – A log of system events (such as port-state change to up or down, and so on) and
alarms. RMON Group 9 also specifies the action to be taken if an alarm threshold is exceeded.
See "Network Monitoring" on page B-1 for information about setting and displaying the RMON statistics.
Syslog Logging
In addition to the event and alarm logs provided by RMON, Foundry devices contain a Syslog agent that can write
log messages to a local buffer and optionally to a third-party SyslogD server. The Syslog feature can write
messages at the following severity levels:
• Emergencies
• Alerts
• Critical
• Errors
• Warnings
• Notifications
• Informational
• Debugging
The device automatically writes the Syslog messages to a local buffer. If you specify the IP address or name of a
SyslogD server, the device also writes the messages to the SyslogD server. The default facility for messages
written to the server is "user". You can change the facility if needed. You also can change the number of entries
that can be stored in the local buffer. The default is 50. Foundry devices do not have a limit to the number of
messages that can be logged on a remote SyslogD server.
NOTE: You can specify only one facility.
See "Configuring the Syslog Service" on page 10-14 for configuration information.
Ping and Traceroute Facilities
After you configure an IP address for the device, you can test the device's network connections using the following
facilities:
• Ping – You can send a test packet to a host's IP address or host name. If the packet reaches the host, the
host generally sends a reply packet to let you know the host received your ping. If the host does not reply
within a specified interval, the Foundry device re-attempts the ping up to a specified number of times.
• Traceroute – On Foundry Layer 2 Switches and Layer 3 Switches, you can trace the IP path to a host. The
traceroute feature displays a list of all the intervening router hops the traceroute request traversed to reach
the host.
