xStack DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch
136
Area ID
Allows the entry of an OSPF Area ID configured above.
Router Priority (0-
255)
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.
Hello Interval (1-
65535)
Allows the specification of the interval between the transmission 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.
Dead Interval (1-
65535)
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.
State
Allows the OSPF interface to be disabled for the selected area without changing the
configuration for that area.
Auth Type
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 Table Configuration
menu. 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.
Password/Auth. Key
ID
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.
Metric (1-65535)
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.
DR State
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.
DR Address
The IP address of the aforementioned Designated Router.
Backup DR Address
The IP address of the aforementioned Backup Designated Router.
Transmit Delay
A read only field that denotes the estimated time to transmit a Link State Update
Packet over this interface, in seconds.
Retransmit Time
A read only field that denotes the time between LSA retransmissions over this
interface, in seconds.
