Users Guide

– The port channel link MTU and IP MTU must be less than or equal to the link MTU and IP MTU values
congured on the channel members. For example, if the members have a link MTU of 2100 and an IP MTU
2000, the port channel’s MTU values cannot be higher than 2100 for link MTU or 2000 bytes for IP MTU.
• VLANS
– All members of a VLAN must have same IP MTU value.
– Members can have dierent link MTU values. Tagged members must have a link MTU 4 bytes higher than
untagged members to account for the packet tag.
– The VLAN link MTU and IP MTU must be less than or equal to the link MTU and IP MTU values congured
on the VLAN members. For example, the VLAN contains tagged members with a link MTU of 1522 and IP
MTU of 1500 and untagged members with link MTU of 1518 and IP MTU of 1500. The VLAN’s link MTU
cannot be higher than 1518 bytes and its IP MTU cannot be higher than 1500 bytes.
