C6576M ATM T3 Interface Dialog Box Chapter 5 Physical Object Dialog Boxes EIGRP Area IS-IS Area • Trans. Priority-The priority of this interface. Used in multiaccess networks, this field is used in the designated router election algorithm. The value 0 signifies that the router is not eligible to become the designated router on this particular network. In the event of a tie in this value, routers will use their router ID as a tie breaker. This attribute is read-only. • Trans. Dead (sec)-Number of seconds that a device's hello packets must not have been seen before its neighbors declare the OSPF router down. Must be consistent among all routers on an attached network.

Physical Object Dialog Boxes
C6576M ATM T3 Interface Dialog Box
Trans. Priority—The priority of this interface. Used in multiaccess networks, this field is used in the
designated router election algorithm.
The value 0 signifies that the router is not eligible to become
the designated router on this particular network. In the event of a tie in this value, routers will use
their router ID as a tie breaker. This attribute is read-only.
Trans. Dead (sec)—Number of seconds that a device’s hello packets must not have been seen before
its neighbors declare the OSPF router down. Must be consistent among all routers on an attached
network. This attribute is read-only.
Trans. Delay (sec)—Estimated number of seconds it takes to send a link-state update packet this
interface. This attribute is read-only.
Retrans. Interval (sec)—The number of seconds between link-state advertisement retransmissions
for adjacencies belonging to this interface.
This value also is used when retransmitting database
description and link-state request packets. This attribute is read-only.
EIGRP Area
The EIGRP area describes the EIGRP configuration of the interface on each active autonomous system.
This area contains the following information:
EIGRP Interface Table—Lists the active EIGRP routing processes on the router. Each routing
process handles routing updates for a single autonomous system. The routing process only is active
if it is deployed on at least one network.
Hold Time (sec)—Hold time during which the device will wait for a hello packet to be received on
the specified interface and EIGRP autonomous system number. The hold time should be at least
three times the hello interval.
Bandwidth Utilization (%)—Percentage of bandwidth that may be used by EIGRP on the interface.
Values greater than 100 percent may be configured; this can be useful if the bandwidth is set
artificially low for other reasons.
Hello Interval (sec)—Frequency at which the device will send hello packets on the specified
interface and EIGRP autonomous system number.
IS-IS Area
The IS-IS area contains the following information:
ISIS Enabled—Indicates whether or not IS-IS routing is enabled on the interface. This attribute is
read-only.
Area Tag—Identifies the IS-IS routing area that the interface participates in. If multiarea IS-IS is
configured on the device, the IS-IS area must be named; otherwise, this value may be an implicit
null tag. This attribute is read-only.
Level 1 Hello Interval—Length of time between hello packets generated on the interface for level 1
routing. With smaller hello intervals, topological changes are detected faster, but there is more
routing traffic.
Level 1 Metric—Cost of the interface for IS-IS level 1 (intra-area) route calculation.
Level 1 Priority—Level 1 priority. The priority is used to determine which router on a LAN will be
the designated router or Designated Intermediate System (DIS). The router with the highest priority
will become the DIS. In the case of equal priorities, the highest MAC address breaks the tie.
Level 2 Hello Interval—Length of time between hello packets generated on the interface for level 2
routing.
