Working with Links
Status Summary Tab: Status Information
To view status information for the selected link, select the Status Summary tab.
The Status Information sub-section displays the following information for the
selected link:
•Last Status Change—Date and time that the status of the link last changed.
•Status—Current status of the link. Possible values are:
–
Active (green ball)—The link is currently fully functional.
–
Blocked (red ball)—Traffic on this link is disabled by protocol.
–
Failed (red ball)—An error is preventing traffic from flowing on this
link, or the associated linkset has been set to Shutdown status.
A link can be Failed from an MTP3 perspective, but control messages
might still be sent or received on the link, resulting in changing
packet/second and bit/second rates. The rates might also be different at
each end of the link, depending on the reason for the failure and the
timing related to each endpoint.
–
InhibitLoc (blue ball)—A local ITP administrator has set the link to
prevent traffic from flowing.
–
InhibitRem (blue ball)—A remote ITP administrator has set the link to
prevent traffic from flowing.
–
Shutdown (blue ball)—An ITP administrator has set the link to prevent
traffic from flowing.
–
Unknown (red ball)—Either the node associated with this link has failed
to respond to an SNMP request, or SGM found that the link no longer
exists.
When you physically delete a link, the Status field displays Unknown
until you delete the link from the SGM database.
–
Warning (yellow ball)—The link is active and traffic is flowing, but one
or more of the following situations has occurred:
– The link is congested.
– The link has exceeded the defined Receive Utilization% or Send
Utilization %.
– One or more of the local or remote IP addresses defined for SCTP is
not active.
