LABEL DESCRIPTION
Authentication
Note: OSPF Interfaces must use the same authentication method within the same
area.
Select an authentication method. The choices are Same-as-Area, None (default), Simple and
MD5.
To participate in an OSPF network, you must make the authentication method and/or
password settings the same as the associated area.
Select Same-as-Area to use the same authentication method within the area and set the
related fields when necessary.
Select None to disable authentication. This is the default setting.
Select Simple and set the Key field to authenticate OSPF packets transmitted through this
interface using simple password authentication.
Select MD5 and set the Key ID and Key fields to authenticate OSPF packets transmitted
through this interface using MD5 authentication.
Key ID When you select MD5 in the Authentication field, specify the identification number of the
authentication you want to use.
Key When you select Simple in the Authentication field, enter a password eight-character long.
Characters after the eighth character will be ignored.
When you select MD5 in the Authentication field, enter a password 16-character long.
Cost The interface cost is used for calculating the routing table. Enter a number between 1 and
65535. The default interface cost is 15.
Priority The priority you assign to the interface is used in router elections to decide which router is going
to be the Designated Router (DR) or the Backup Designated Router (BDR). You can assign a
number between 0 and 255. A priority of 0 means that the router will not participate in router
elections.
Retransmit Specify how long (in seconds) the Switch should wait for an acknowledgment packet from the
Interval interface's neighbor device before retransmitting link-state advertisements (LSAs) on the
interface. The valid range for retransmitting is between 1 and 65535. The default value is 5
seconds.
Transmit Delay Set the estimated time (in seconds) that is required to transmit a link-state update packet on the
interface. The valid range for transmitting delay is between 1 and 65535. The default value is 1
second.
Hello Interval Specify how often (in seconds) the Switch sends hello packets on the interface to check if the
interface's neighbor devices still exist. The valid range for hello interval is between 1 and 65535.
The default value is 10 seconds.
Dead Interval Specify how long (in seconds) the Switch should wait for a hello packet from the interface's
neighbor device before declaring that the neighbor device is not available. The valid range for
dead interval is between 1 and 65535. The default value is 40 seconds.
Add Click Add to save your changes to the Switch's run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to save
your changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
Clear Click Clear to set the above fields back to the factory defaults.
Index This field displays the index number for an interface.
Network This field displays the IP interface information.
Area ID This field displays the area ID (in an IP address format with dotted decimal notation) of an area
to associate the interface to that area.
Authentication This field displays the authentication method used (Same-as-Area, None, Simple or MD5).
