ESH—Sets the End System Hello (ESH) propagation frequency. End system NEs transmit
–
ESHs to inform other ESs and ISs about the NSAPs it serves. The default is 10 seconds. The
range is 10 to 1000 seconds.
ISH—Sets the Intermediate System Hello PDU propagation frequency. Intermediate system
–
NEs send ISHs to other ESs and ISs to inform them about the unlocked NETs it serves. The
default is 10 seconds. The range is 10 to 1000 seconds.
IIH—Sets the Intermediate System to Intermediate System Hello PDU propagation frequency.
–
The IS-IS Hello PDUs establish and maintain adjacencies between ISs. The default is 3 seconds.
The range is 1 to 600 seconds.
IS-IS Cost—Sets the cost for sending packets on the LAN subnet. The IS-IS protocol uses the
–
cost to calculate the shortest routing path. The default metric cost for LAN subnets is 20. It
normally should not be changed.
EOC (DCC Termination Failure) and LOS (Loss of Signal) alarms are present until you create
all network DCC terminations and put the DCC termination optical ports in service.
There are four possibilities for the appearance of DCCs: green/solid, green/dashed, gray/solid,
gray/dashed. DCC appearance corresponds to the following states: active/routable,
active/nonroutable, failed/routable, or failed/nonroutable. Circuit provisioning uses
active/routable links. Selecting a node or span in the graphic area displays information about the
node and span in the status area.
This task verifies that a 1+1 protection group will switch traffic properly.
