dot3ExtPkgObjectNumberOfLLIDs
Module: DOT3-EPON-MIB
OID (symbolic): DOT3-EPON-MIB::dot3ExtPkgObjectNumberOfLLIDs
OID (numeric): 1.3.6.1.2.1.155.1.4.1.1.1.3
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: A read only object that indicates the number of registered LLIDs. The initialization value is 0. This object is applicable for an OLT with the same value for all virtual interfaces and for an ONU. The LLID field, as defined in the [802.3ah], is a 2-byte register (15-bit field and a broadcast bit) limiting the number of virtual links to 32768. Typically the number of expected virtual links in a PON is like the number of ONUs, which is 32-64, plus an additional entry for broadcast LLID (with a value of 0xffff). At the ONU the number of LLIDs for an interface is one.
What is dot3ExtPkgObjectNumberOfLLIDs?
This reports how many LLIDs (logical links) are currently registered on this interface, starting at 0; at an ONU it's always one, while at an OLT it reflects how many ONUs are actively registered. Admins watch this to confirm the expected number of subscriber ONUs are actually online on a given OLT port.
