SET MTU ON VCS

Does anyone know where and what command to set the MTU size on the VCS Control??? I need to change it from 1500 to 1300.

Thank you.

Re: SET MTU ON VCS

Hi Chet,

login to root on the VCS and run the below command.

# ifconfig eth0 mtu 1300

to make the change permanent modify the file '/etc/network/interfaces' using vi command and make an entry "mtu 1300".

below is the command when i did on my vcs and when i read the same file using "cat" command.

~ # cat /etc/network/interfaces

auto lo

iface lo inet loopback

auto eth0

iface eth0 inet static

    address 10.106.93.178

    netmask 255.255.255.192

    network 10.106.93.128

    up /sbin/ethtool -s eth0 autoneg on

    mtu 1300

after making the changes you can just reboot the machine.

To verify run the command 'ifconfig eth0' and verify the mtu size.

Re: SET MTU ON VCS

Hi Chet,

when you login as root run the command 'pwd'. you should see a output like this.

~ # pwd

/tandberg

if you are not in '/tandberg'  then you have to first go in that and then do the above steps.
