Command Line Interface Reference for the ProSafe 7300S Series Layer-3 Stackable Switches, OSPF advertises the IP MTU in the Database Description packets it sends to its neighbors during database exchange. If two OSPF neighbors advertise different IP MTUs, they will not form an adjacency (unless OSPF has been instructed to ignore differences in IP MTU with the ip ospf mtu-ignore command.) Note: The IP MTU size refers to the maximum size of the IP packet (IP Header + IP payload). It does not include any extra bytes that may be required for Layer-2 headers. To receive and process packets, the Ethernet MTU must take into account the size of the Ethernet header. The minimum IP MTU is 68 bytes.The maximum IP MTU is 1500 bytes. Default 1500 bytes Format ip mtu Mode Interface Config 14.2.9.1 no ip mtu This command resets the ip mtu to the default value. Format no ip mtu Mode Interface Config 14.2.10 encapsulation This command configures the link layer encapsulation type for the packet. Acceptable values for are ethernet and SNAP. The default is ethernet. Format encapsulation {ethernet | snap} Mode Interface Config Note: Routed frames are always ethernet encapsulated when a frame is routed to a VLAN. 14-12 v3.0, January 2008 Routing Commands

Routing Commands
v3.0, January 2008
OSPF advertises the IP MTU in the Database Description packets it sends to its neighbors
during database exchange. If two OSPF neighbors advertise different IP MTUs, they will
not form an adjacency (unless OSPF has been instructed to ignore differences in IP MTU
with the ip ospf mtu-ignore command.)
The minimum IP MTU is 68 bytes.The maximum IP MTU is 1500 bytes.
Default
1500 bytes

14.2.10 encapsulation
This command configures the link layer encapsulation type for the packet. Acceptable

are ethernet and SNAP. The default is ethernet.

Note:
The IP MTU size refers to the maximum size of the IP packet (IP Header +
IP payload). It does not include any extra bytes that may be required for
Layer-2 headers. To receive and process packets, the Ethernet MTU must
take into account the size of the Ethernet header.
Note:
Routed frames are always ethernet encapsulated when a frame is routed to
a VLAN.
