Allows the entry of a number between 0 and 255 representing the OSPF priority of the
selected area. If a Router Priority of 0 is selected, the Switch cannot be elected as the
Designated Router for the network.
Allows the specification of the interval between the transmissions of OSPF Hello packets, in
seconds. Between 1 and 65535 seconds can be specified. The Hello Interval, Dead Interval,
Authorization Type, and Authorization Key should be the same for all routers on the same
network.
Allows the specification of the length of time between the receipt of Hello packets from a
neighbor router before the selected area declares that router down. An interval between 1
and 65535 seconds can be specified. The Dead Interval must be evenly divisible by the
Hello Interval.
Allows the OSPF interface to be disabled for the selected area without changing the
configuration for that area.
This field can be toggled between None, Simple, and MD5 using the space bar. This allows
a choice of authorization schemes for OSPF packets that may be exchanged over the OSPF
routing domain.
None specifies no authorization.

Simple uses a simple password to determine if the packets are from an

authorized OSPF router. When Simple is selected, the Auth Key field allows the
entry of an 8-character password that must be the same as a password
configured on a neighbor OSPF router.
MD5 uses a cryptographic key entered in the MD5 Key Settings window. When

MD5 is selected, the Auth Key ID field allows the specification of the Key ID as
defined in the MD5 configuration above. This must be the same MD5 Key as
used by the neighboring router.
Enter a Key ID of up to 5 characters to set the Auth. Key ID for either the Simple Auth Type
or the MD5 Auth Type, as specified in the previous parameter.
This field allows the entry of a number between 1 and 65,535 that is representative of the
OSPF cost of reaching the selected OSPF interface. The default metric is 1.
The user may select Active or Passive for this OSPF interface. Active interfaces actively
advertise OSPF to routers on other Intranets that are not part of this specific OSPF group.
Passive interface will not advertise to any other routers than those within its OSPF intranet.
When this field is disabled, it denotes an active interface.
DR State is a read-only field describing the Designated Router state of the IP interface. This
field many read DR if the interface is the designated router, or Backup DR if the interface is
the Backup Designated Router. The highest IP address will be the Designated Router and is
determined by the OSPF Hello Protocol of the Switch.
The IP address of the aforementioned Designated Router.
The IP address of the aforementioned Backup Designated Router.
A read-only field that denotes the estimated time to transmit a Link State Update Packet over
this interface, in seconds.
A read-only field that denotes the time between LSA retransmissions over this interface, in
seconds.
