Module: CASCADE-MIB

OID (symbolic): CASCADE-MIB::pportInterface

OID (numeric): 1.3.6.1.4.1.277.1.4.2.1.30

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: Actual interface connected to Multi-Interface Port or ATM-IWU.

What is pportInterface?

This reports the actual physical interface type, such as V.35, X.21, EIA-530, E1 coax, SONET, or a specific fiber mode, that the switch has detected attached to this Multi-Interface Port or ATM-IWU card. Because Multi-Interface cards accept several different cable/interface standards on the same physical slot, this read-only value tells you what the switch actually sees plugged in right now, which is the first thing to check when a port will not come up despite correct configuration. If pportAdminInterface was configured for v35 but pportInterface reads back as none, no interface adapter or cable of the expected type is actually detected on this port.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.30
snmpwalk -v2c -c public <target> CASCADE-MIB::pportInterface

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.30.1
snmpget -v2c -c public <target> CASCADE-MIB::pportInterface.1
