aclEntryPrefixLength
Module: CM-SYSTEM-MIB
OID (symbolic): CM-SYSTEM-MIB::aclEntryPrefixLength
OID (numeric): 1.3.6.1.4.1.2544.1.12.2.1.4.2.1.8
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: This object describe the ipv6 Prefix length.
What is aclEntryPrefixLength?
This Integer32 value (0-128) is the IPv6 prefix length that, combined with aclEntryNetworkIpv6Addr, determines how many leading bits of an address must match for the ACL entry to apply. An admin adjusts it to control how broad or narrow the permitted IPv6 range is. For example, setting the prefix length to 128 restricts the rule to a single host address, while a shorter length like 64 would cover an entire subnet.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2544.1.12.2.1.4.2.1.8 snmpwalk -v2c -c public <target> CM-SYSTEM-MIB::aclEntryPrefixLength
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2544.1.12.2.1.4.2.1.8.1 snmpget -v2c -c public <target> CM-SYSTEM-MIB::aclEntryPrefixLength.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.2544.1.12.2.1.4.2.1.8.1 i <value>
