subPortNumber

Module: ZHONE-INTERFACE-TRANSLATION-MIB

OID (symbolic): ZHONE-INTERFACE-TRANSLATION-MIB::subPortNumber

OID (numeric): 1.3.6.1.4.1.5504.3.5.3.1.4

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: The subPortNumber is used to identify multiple logical ports on a physical that require their own interface number, e.g. DS1s on a DS3 port.

Note that multiple protocol layers such as IP over ATM do not require unique interface numbers and are handled by the standard ifStackTable mechanism.

Subport 0 is reserved to designate that a physical port has no subport and hence a single interface number.

What is subPortNumber?

Identifies a specific logical sub-interface on a physical port when one port carries multiple interfaces, such as individual DS1s on a DS3 port; a value of 0 means the port has no subport and only one interface.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5504.3.5.3.1.4
snmpwalk -v2c -c public <target> ZHONE-INTERFACE-TRANSLATION-MIB::subPortNumber

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.5504.3.5.3.1.4.1
snmpget -v2c -c public <target> ZHONE-INTERFACE-TRANSLATION-MIB::subPortNumber.1
