atmCardActivePortMask

Module: CARD-MIB

OID (symbolic): CARD-MIB::atmCardActivePortMask

OID (numeric): 1.3.6.1.4.1.5812.2.7.1.2

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 2 ports for an ATM card, this can take the range of values from 0 to 3.

What is atmCardActivePortMask?

This read-only value is a bitmap (0-3) of which of the ATM card's 2 ports are active, where a set bit in position N-1 means port N has been created via a Port Create management operation. Since ATM cards only have 2 ports, the useful range is much smaller than the equivalent Ethernet port mask.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5812.2.7.1.2
snmpwalk -v2c -c public <target> CARD-MIB::atmCardActivePortMask

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.5812.2.7.1.2.1
snmpget -v2c -c public <target> CARD-MIB::atmCardActivePortMask.1
