Chapter 5 Physical Object Dialog Boxes C6576M OSM Serial Subinterface Dialog Box EIGRP Area ISIS 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. If more than one router has the same value for this field, the routers use their router ID as a tie breaker. • 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. • Trans. Delay (sec)-The estimated number of seconds it takes to transmit a link state update packet over this interface. • Retrans. Interval (sec)-The number of seconds between link-state advertisement retransmissions for adjacencies belonging to this interface. This value is also used when retransmitting database description and link-state request packets. The EIGRP Area of the C6576M Ethernet Interface dialog box provides the following information: • EIGRP Interface Table-Describes the EIGRP configuration of the interface on each active autonomous system. The EIGRP parameters of the interface on an autonomous system may be explicitly configured even if EIGRP routing updates in the autonomous system are not currently carried on the interface. • Bandwidth Utilization (%) -The percentage of the interface bandwidth that the EIGRP protocol can use. • Hello Interval (sec)-Frequency at which the device will send hello packets on the specified interface and EIGRP autonomous system number. • 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. The ISIS area of the C6576M Ethernet Interface dialog box provides the following information: • ISIS Enabled-Indicates whether or not IS-IS routing is enabled on the interface: - true-IS-IS routing is enabled. - false-IS-IS routing is disabled. • Area Tag-The IS-IS routing area in which the interface participates. 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. • Level 1 Hello Interval-Length of time between hello packets generated on the interface for level 1 routing. • Level 2 Hello Interval-Length of time between hello packets generated on the interface for level 2 routing. • Level 1 Metric-Cost of the interface for IS-IS level 1 (intra-area) route calculation. • Level 2 Metric-Cost of the interface for IS-IS level 2 (inter-area) route calculation. • Level 1 Priority-The priority is used to determine which router on a LAN will be the designated router or designated intermediate system (DIS).
