ISP/mpls networks, MTU limitation vs. AOS/CX and MACSec
Based on the ISP requirement/limitation they can only handle a Max Frame Size: 9192;
Inside the mpls network.
sh jumbos (AOS)
Configured : Max Frame Size : 9216 IP-MTU : 9198
In Use : Max Frame Size : 9216 IP-MTU : 9198
The CX states on a Physical interface:
The CX states on a SVI:
SW(config-if-vlan)# ip mtu
What should the Max Frame Size/IP-MTU be set to on the SVI and or Physical,
for all MacSec frames to be traversed, understanding there is an overhead for the MacSec.
However is it necessary to decrease the OS,(2930F 's) Max Frame Size of 9216 equally ?,
Alternatively, will this do the trick on a OS switch:
