hh3cEponUniVLANTrunkAllowListLow

Module: HH3C-EPON-UNI-MIB

OID (symbolic): HH3C-EPON-UNI-MIB::hh3cEponUniVLANTrunkAllowListLow

OID (numeric): 1.3.6.1.4.1.25506.2.42.5.1.1.1.9

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-write

Description: Each octet within this value specifies a set of eight vlans, with the first octet specifying vlans 1 through 8, the second octet specifying vlans 9 through 16, etc. Within each octet, the most significant bit represents the highest numbered VLAN, and the least significant bit represents the lowest numbered VLAN. Thus, each allowed vlan of the trunk port is represented by a single bit within the value of this object. If that bit has a value of '1' then that vlan is allowed in the set of vlans. the vlan is not allowed if its bit has a value of '0'.

What is hh3cEponUniVLANTrunkAllowListLow?

Bitmap covering VLANs 1-2048 (8 VLANs per octet, MSB = highest numbered) that this trunk UNI port is allowed to carry; a bit set to 1 means that VLAN is permitted on the trunk.
