Switch Configuration

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.
