etherCardActivePortMask

Module: CARD-MIB

OID (symbolic): CARD-MIB::etherCardActivePortMask

OID (numeric): 1.3.6.1.4.1.5812.2.6.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This returns a mask of active ports. An active port is one that has been created via a Port Create MO. A value of 1 in bit position N-1 indicates that port N has been created. For example, if port 1 has been created, then bit 0 is asserted. Since there are 16 ports, this can take the range of values from 0 to 65535.

What is etherCardActivePortMask?

This read-only value is a bitmap (0-65535) of which of the card's 16 Ethernet ports are active, where a set bit in position N-1 means port N has been created via a Port Create management operation. An admin can decode this bitmap to see exactly which physical ports are provisioned on the card.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5812.2.6.1.2
snmpwalk -v2c -c public <target> CARD-MIB::etherCardActivePortMask

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.5812.2.6.1.2.1
snmpget -v2c -c public <target> CARD-MIB::etherCardActivePortMask.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> etherCardActivePortMask.1
