Usage Information
If the packet includes a Layer 2 header, the dierence between the link MTU and IP MTU (ip mtu command)
must be enough bytes to include the Layer 2 header.
• The IP MTU is adjusted automatically when you congure the Layer 2 MTU with the mtu command.
When you enter the no mtu command, The Dell Networking OS reduces the IP MTU value to 1536 bytes.
Link MTU and IP MTU considerations for port channels and VLANs are as follows.
port channels:
• All members must have the same link MTU value and the same IP MTU value.
• The port channel link MTU and IP MTU must be less than or equal to the link MTU and IP MTU values
congured 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 dierent 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 congured on
the VLAN members. For example, the VLAN contains tagged members with 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.
The following shows the dierence between Link MTU and IP MTU.
