[edit] Foundry

Unlike juniper all operational (like show) commands work in configuration mode.

Foundries don't take ssh keys and need passwords. boo!

show interfaces brief - shows interfaces with status, speed, and description (port-name)
Port  Link    L2 State  Dupl Speed Trunk Tag Priori MAC            Name           
1/1   Up      Forward   Full 1G    None  No  level0 0012.f2c5.5600 db63           
1/2   Up      Forward   Full 1G    None  No  level0 0012.f2c5.5600 db64   

| include - grep

sh mac-address - shows mac addresses
sh mac-address ethernet x/x - shows mac for interface x/x

conf t - configuration mode
SSH@csw1-sdtpa(config)#

show run - shows configuration

int ether 12/1 - go into configuration for that interface

port-name - assigns description
disable - turns port off
enable - turns port on
exit - moves you up a level

after configuration - ALWAYS type "write mem" 
must do write mem OUT of config mode
write mem - saves to hard drive the config, incase the box reboots

in conf mode - 
Foundries configure immediately - when you've typed the command, it's live!
vlan 2 - moves into vlan 2's configuration mode
unt eth X/X - puts X/X into that vlan as untagged
no unt eth X/x - takes X/X out of vlan
 

if you get the error "error - port ethe 1/25 do not belong to default vlan" that means the port is in another vlan and must be removed first

[edit] Juniper

Junipers take ssh keys. huzzah!

Juniper has operational mode and configuration mode.

operational mode - 
{master:8}       
lcarr@asw-a-eqiad> 
configuration mode - 
{master:8}[edit]
lcarr@asw-a-eqiad# 

[edit] Operational commands

show ethernet-switching table  - shows mac addresses
show ethernet-switching table interface - shows mac addresses for that interface
show ethernet-switching table vlan  - shows mac addresses for vlan
show interfaces descriptions - 
Interface       Admin Link Description
ge-1/0/0        up    up   ms1001

show interfaces terse - shows interfaces with ip's in a very short format

show interface ge-1/0/0 (extensive)- shows interfaces in more detail

monitor interface xe-1/1/0 - shows interface in a real-time updating mode (errors, bits, etc)

show log messages | last 20 - shows log with info

[edit] Config commands

Junipers configure after you confirm - you can configure and then double check

• configure - puts you in config mode
• exit - takes you up one level (or out of) config mode
• top - takes you to the top level of config mode
• show - shows you configuration below that level
