Description: This entry holds a count of the VCI bits supppoted my this ATM card.

What is pportAtmNumBitsVCI?

This reports how many bits this ATM card's hardware allocates to the VCI field for this port. This value determines the maximum number of distinct virtual channels (2 to the power n) this specific port's card can address per virtual path, which matters when planning how many PVCs or SVCs can be provisioned per VPI on this port. A card reporting 16 VCI bits here supports up to 65,536 VCI values per VPI on this port, far more than a typical deployment would need, whereas a smaller card might report fewer bits and cap VC scaling accordingly.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.66
snmpwalk -v2c -c public <target> CASCADE-MIB::pportAtmNumBitsVCI

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.66.1
snmpget -v2c -c public <target> CASCADE-MIB::pportAtmNumBitsVCI.1
