Some helpful advice from our Nortel account SE on how to wrangle and secure an 8600:
On a dual Fabric/CPU 8600 you would perform the following commands. Assumes direct connection as IP addressing will be cleared:
Defaulting the Standby CPU:
Defaulting the Primary CPU after Standby is defaulted:
Example: copy 126.96.36.199:default.cfg /flash/config.cfg
You can view the contents of a configuration file using the "more" command from the 8600 console - this will help keep things straight if your are unsure of which file is which. If you capture your screen, you will have a flat text file of your configuration.
Example: more /flash/config.cfg
CLI commands to change the console/Telnet password:
The following commands change the console/Telnet login name and the password
config cli password ro < username> [< password>]
Example - to change read/write/all password:
config cli password rwa ron 190xyz
To display information about the access levels for login and password, type:
For each access level, the default login and passwords are as follows:
Passport_8100:5# show cli password
ACCESS LOGIN PASSWORD
Device Manager commands to change the console/Telnet password:
Note: On a default 8600, fill in Read and Write community string on DM fields as "secret" for authority to set these access levels - otherwise the fields will be blank and change access denied.
SNMP from CLI:
config sys set snmp commands
The config sys set snmp commands allow you to configure the SNMP settings for your switch.
config sys set snmp followed by:
info Displays the current SNMP settings
community <ro|rw|l1|l2|l3|rwa> < commstr> Sets the SNMP community string for the selected community:
DEFUALT COMMUNITY STRINGS
del-trap-recv < ipaddr> Deletes the SNMP trap receiver. ipaddr is the IP address of the trap receiver.
trap-recv < ipaddr> <v1|v2c> < commstr> Sets an SNMP trap receiver.
Saving Configurations from CLI:
To synchronize, execute save config and save config standby in succession. Re-execute commands with pcmcia in path if desired.
save config - saves running configuration to /flash/config.cfg
save config file /pcmcia/config.cfg - saves running configuration to pcmcia with a filename of config.cfg
save config standby /flash/config.cfg - saves running configuration to /flash/config.cfg on standby CPU.
save config standby /pcmcia/config.cfg - saves running configuration to standby CPU pcmcia with a filename of config.cfg.
Options: you can save bootconfig information in the same manner - "save bootconfig"
