DES-6500 Chassis-based Layer 3 Ethernet Switch Manual
169
Parameter
Description
Interface Name
Displays the of an IP interface previously configured on the Switch.
IP Address
Displays the IP address of the interface and its current status (Link Up / Link Down)
Network Medium
Type
A read only field describing the type of network medium in use. This field will only read
Broadcast due to OSPF configurations permanently set in the Switch.
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 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.
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.
