Switches may only be accessed through Cluster 0. Gain access to cluster 0 by ssh'ing through gimel -> sgehead -> then ssh to your desired switch.
Logging into the Switch
To log into cluster 0, log into gimel first from any computer on the network. Then, log into sgehead with:
ssh -l <username> sgehead.bkslab.org
Once on sgehead, log into your desired switch with ssh:
ssh switch-1-1 || ssh switch-3-1
Switch passwd is cluster0formula with switch name/number.
Changes to Configuration
When using command line to make configuration changes to the switch, the changes will be written to the Running-config file in volatile memory. These changes will not be saved permanently. To make your changes permanent, you must use the write memory command.
switch-3-1# write memory
Any reboot without using the switch's write memory command will erase all changes since the last write memory command or the last reboot.
VLAN Port Assignment
Ports on the switch may be chosen to be assigned to a specific VLAN. They can be tagged, untagged, or not assigned. The terminology can be a bit tricky but here is the jist.
Tagged - Port is used for Interswitch Link
Untagged - Port is used to connect to a host
No - No VLAN assigned.
