DGS-3312SR Stackable Gigabit Layer 3 Switch
145
Parameter
Description
Interface Name
Displays the of an IP interface previously configured on the Switch.
IP Address
The IP Address of the Interface name stated above.
Area ID
Allows the entry of an OSPF Area ID configured above.
Router Priority
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
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
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 Setting
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.
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
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.
