Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
Each interface has a default maximum packet size or MTU size. This number generally defaults to the largest
size possible for that interface type. On serial interfaces, the MTU size varies, but cannot be set smaller than
64 bytes.
The MTU for the bridge domain includes only the payload of the packet. For example, a configured bridge
MTU of 1500 allows tagged packets of 1518 bytes (6 bytes DA, 6 bytes SA, 2 bytes ethertype, or 4 bytes
qtag).
Bridge wide MTU is not enforced on the data traffic.Note
