Since ALA-A uses Dot1q encapsulation, the SAP MTU must be set to 1518 to be able to accept a
1514 byte service frame (see
for MTU default values). Each SDP MTU must be set to at
least 1514 as well. If ALA-A’s network port (1/3/1) is configured as an Ethernet port with a GRE
SDP encapsulation type, then the MTU value of network ports 1/3/1 and 1/5/1 must
each
be at
least 1556 bytes (1514 MTU + 28 GRE/M 14 Ethernet). Finally, the MTU of ALA-B’s
SAP (access port 1/1/1) must be at least 1514, as it uses null encapsulation.
