Table 553 priority command
Description This command configures the OSPF packet size used on this interface. If this parameter is not
configured OSPF derives the MTU value from the MTU configured (default or explicitly) in the
following contexts:
configure>port>ethernet
If this parameter is configured, the smaller value between the value configured here and the
MTU configured (default or explicitly) in an above-mentioned context is used.
To determine the actual packet size add 14 bytes for an Ethernet packet and 18 bytes for a
tagged Ethernet packet to the size of the OSPF (IP) packet MTU configured in this command.
Use the no form of this command to revert to default.
Default no mtu — Uses the value derived from the MTU configured in the configure>port context.
Parameters bytes — The MTU to be used by OSPF for this logical interface in bytes.
Values: 512 — 9198 (9212-14) (Depends on the physical media)

Description This command adds the passive property to the OSPF interface where passive interfaces are
advertised as OSPF interfaces but do not run the OSPF protocol.
By default, only interface addresses that are configured for OSPF will be advertised as OSPF
interfaces. The passive parameter allows an interface to be advertised as an OSPF interface
without running the OSPF protocol.
While in passive mode, the interface will ignore ingress OSPF protocol packets and not
transmit any OSPF protocol packets.
The no form of the command removes the passive property from the OSPF interface.
Default Service interfaces defined in configure>router>service-prefix are passive.
All other interfaces are not passive.
