Here is a quick cheat sheet of commands that I use during the initial setup of an Extreme switch.

 

Showing Configuration:

show config
show config detail

NTP, Clock and Time
You can see clock and time by either the show system or show switch commands
configure timezone name EST -360 autodst name EDT
enable ntp
configure ntp server add 192.168.1.200
configure time 1 19 2016 7 55 55
Show Switch time in use counters

show odometers

See which config is used:

show switch

Factory reset:

unconfigure switch – Resets everything back except odometer, clock, and user accounts/passes
unconfigure switch all – Resets everything including users

admin and blank password

Setting Password

con mgmt ipa 10.10.10.9/24
con vlan default ipaddress 10.10.10.9/24

Set Default Gateway

configure iproute add default 10.x.x.x

Enable Web Interface:

LACP

show lacp lag
enable sharing port grouping port_list {algorithm [address-based {L2 | L3 | L3_L4| custom} | port-based }]} {lacp | health-check}
configure ports partition 4x10G
configure lacp member-port 1 port priority 32768
VLANs:

configure vlan ptp_gm tag 40
configure vlan VLANname add port 1 untagged

Updating XOS Image:

download image 10.10.10.10 summitX-15.4.1.3-patch1-9.xos
install the software after it loads by typing Y when prompted if you want to install the load
When the download and install finishes, instruct the switch to reboot by typing reboot

Selecting boot image:

use image primary

use image secondary

 

These are the commands I have come across that I find useful, I will add additional as I find them.  If you have any you think should be added please leave them in the  comments below.
