exNetModuleLinkStatus
Module: DAVID-MIB
OID (symbolic): DAVID-MIB::exNetModuleLinkStatus
OID (numeric): 1.3.6.1.4.1.66.1.3.2.2.1.1.51
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Compresses the link status of all of this module's ports into a two-byte integer value. Sums f(x) as x goes from 1 to number of ports, where f(x) = 0 for port with link status test passed (link active) and f(x) = exp(2,x-1) for port with link status test failed (link inactive).
For ports with link status test disabled, zero is returned.
For example, if link status is active on all ports, the value returned is zero. If link status for ports 3 and 7 is inactive and the rest of the ports have active link status, the value returned is (2^(3-1) + 2^(7-1)) = (4 + 64) = 68.
What is exNetModuleLinkStatus?
Encodes the link-active/inactive state of every port on this module into a single two-byte bitmask, where a bit is set for each port whose link-status test failed (inactive); ports with the test disabled always contribute zero. For example, inactive links on ports 3 and 7 alone produce the value 68 (2^2 + 2^6).
