Valentine subcluster switches (Nortel 4548GT)
The 4500 series Nortel switches are different from all others. A few hints:
- The serial port setting is 9600 8N1 with NO flow control
- Before the serial port will work, the dip switch on the back of the unit may need to be set to "BASE". If it is set to "Unit select" you may not get any reasonable response out of the serial port
- Configuration of the unit, except for its own IP address, initally proceeds ONLY over the IP interfaces, NOT the serial console. However, starting the QuickConfiguration utility and then interrupting it with ^C gets you to a reasonable state. Use ^Y again to enter the console mode.
- If nothing seems to happen, press ^Y
- The local user names (for the web interface) are "RO" and "RW", respectively.

Proposed Configuration
Configure trunk using MLT (LACP?) on ports 47 and 48 (the two right-most ports) and run both VLAN 9 and VLAN 4 tagged over this trunk. All other ports 1-44 are be be untagged ports in VLAN 9.
ena conf t autosave enable mlt 1 name uplink enable member 47-48 vlan create 4 name IPMI type port vlan create 9 name FARMNET type port vlan configcontrol automatic vlan ports 1-46 tagging disable vlan ports 47-48 tagging enable vlan members remove 1 1-48 vlan members 9 1-46 vlan members add 4 47-48 vlan members add 9 47-48
The management interface of the switch can be assigned to VLAN4 now and then configured with the ip address of the switch using:
conf t vlan mgmt 4 ip address 172.20.X.Y ip address netmask 255.255.0.0 ip default-gateway 172.20.255.254 cli password switch serial local cli password switch telnet local cli password switch read-only "LOWIPMIPASSWD" cli password switch read-write "IPMIPASSWD" cli password stack read-only "LOWIPMIPASSWD" cli password stack read-write "IPMIPASSWD" snmp-server community "public" ro snmp-server community "COMPLEXHASH" rw snmp-server contact "grid.sysadmin@nikhef.nl" snmp-server name "farmnet-sw-valentine-XX" snmp-server location "H139"
where farmnet-sw-valentine-01.ipmi.nikhef.nl = 172.20.1.248, -02 = 172.20.1.249, and -03 = 172.20.1.250.
Set the STP leaning mode to fast
