'ip tcp adjust-mss' is available from IOS adventerprisek9-mz.122-33.SRD6 ?

[syjeon]

Hi,

We need to make tunnel interface between HQ and branch in order to allow the traffic through tunnel.

Our C7613 router is using IOS adventerprisek9-mz.122-33.SRD6. Thus, I would like know whether following syntax is acceptable or not.

interface tunnel 0

ip tcp adjust-mss

!

Supervisor: WS-SUP720-3BXL

Can someone check if above command is working or not on above device? we do not have test device to apply.

Thanks.

Hi,

I don't know exactly when the command was introduced into 12.2SR IOS, but we've been using it since 12.2(33)SRB3 so it will be supported in 12.2(33)SRD. Below you can see it configured on a Cisco 7604 running 12.2(33)SRB7.

Why do you attempt to type the command without "enter"?. Use the character "?" to show the help.

Regards.

antonio, thanks for your responding, I would like to do by typing '?' but, we didn't have the device right now to check..

[Steve Fuller]

No need for the ? in this case as you can see from the response above it is supported back in 12.2(33)SRB7.
