Question. I have Aruba VPN controllers 70xx models AOS 6.5.3.3. I have a cyrpto tunnel between two controllers. I read that the default tunnel mtu is 1500 and if I want to change it I have to do a gloabl command "crypto ipsec mtu xxxx". I made a change like this for MTU 1024 for a test and a "show crypto ipsec mtu" shows the new value.
What I want to know is if there is a command that I can see the MTU is set on the actual tunnel between the two controllers? Like a sh crypto ipsec sa perr x.x.x.x. Any MTU settings in these types of commands? I have not been able to locate one.
