Troubleshooting guide

Step 6: As soon as the ethernet port is connected, the upper green LED on

the RJ45 connector will illuminate.

Step 7: When the monitoring line card has received its IP address, it is

reachable. You can ping the card, open a web browser to it, or walk the

SNMP MIB.

Step 8: If you make a mistake and cannot ping the switch, then use the

TFT display to turn static addressing to no and reboot.

To assign an IP address via DHCP:

Step 1. Read the MAC address from the faceplate of the monitoring line

card, and register this MAC address with a static IP address in the DHCP

server configuration file (/etc/dhcpd.conf) on the DHCP server on the

local network. The DHCP server will then serve this static IP address to

the monitoring line card when it boots and asks for it.

The MAC address is a group of 6 hexadecimal numbers separated by

colons, and should begin with 00:60:dd:??:??:??.

Step 2. Connect at least one of the ethernet ports on the monitoring line

card to the LAN. For high availability, the second ethernet port can also be

connected.

The ethernet ports on the monitoring line card are 10/100-Base-T.

Step 3. As soon as the ethernet port is connected, the upper green LED on

the RJ45 connector will illuminate, and the monitoring line card will

immediately start to broadcast DHCP requests. When the monitoring line

card has received its IP address, it is reachable. You can ping the card,

open a web browser to it, or walk the SNMP MIB.

Note: To determine the IP address that was assigned to the monitoring line

card, you can select big_uc from the color-TFT display, or Status->Slot

m from the web interface, or refer to the file /var/state/dhcp/dhcpd.leases

on your DHCP server.

The DHCP client (udhcp) on the monitoring line card does not ask for any

particular lease time. It will accept whatever lease the DHCP server gives

it, and only attempt to renew the lease after reaching half the life of the

lease.

For further details of the SNMP interface, refer to "Does the monitoring

line card in the M3-CLOS-ENCL-* and M3-SPINE-ENCL-* switches

support SNMP?" (http://www.myri.com/cgi-bin/fom?file=383).
