====Change password=====

Change password of admin and user:
<code>
username admin NEWPASSWORD
username user NEWPASSWORD
</code>


====Connect with recent versions of OpenSSH====

The VDX6720 uses an old version of sshd with an old HostKeyAlgorithm that newer versions of ssh no longer allow by default.

To connect to a VDX6720 with ssh you must provide the correct older HostKeyAlgorithm when connecting.

<code>
ssh -o HostKeyAlgorithms=ssh-rsa root@10.10.0.10
</code>


====Start cli from root shell====

When logging in as root you do not have access to the switch management tooling until you start:

<code>
noscli
</code>


====Save config====

<code>
copy running-config startup-config
</code>


====Back-up config====

A VDX6720 does not provide scp, but a cat via ssh redirected to a file can be used for creating a back-up of the current startup-config:

<code>
ssh -o HostKeyAlgorithms=ssh-rsa root@10.10.0.10 "cat /var/config/vcs/scripts/startup-config" > /data/backup/switch04/`date +%Y-%m-%d`\ -\ startup-config
</code>


====Show running-configuration for one interface====

<code>
show running-config int te 4/0/3
</code>


====Edit multiple interfaces at once====

For a range of interfaces:
<code>
conf t
int te 4/0/3-5
# Now enter the configuration commands that should apply to port 3, 4, and 5.
</code>

For 2 interfaces:
<code>
conf t
int te 4/0/1,6
# Now enter the configuration commands that should apply to port 1, and 6.
</code>
====Show media status====

Show the media status of interface 1 on switch with id 4.
<code>
show media te 4/0/1
</code>

Example output for a recognized SFP:
<code>

====Show interface switchport====

Show interface switchport information:

<code>
