Module: S5-CHASSIS-MIB

OID (symbolic): S5-CHASSIS-MIB::s5ChasComIpv6NetMask

OID (numeric): 1.3.6.1.4.1.45.1.6.3.3.1.1.21

Node type: OBJECT-TYPE

Type: Ipv6AddressPrefix

What is s5ChasComIpv6NetMask?

The IPv6 prefix/netmask associated with this component's IPv6 address (s5ChasComIpv6Address); reads 0::0 for components without their own IPv6 stack.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.1.6.3.3.1.1.21
snmpwalk -v2c -c public <target> S5-CHASSIS-MIB::s5ChasComIpv6NetMask

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.45.1.6.3.3.1.1.21.1
snmpget -v2c -c public <target> S5-CHASSIS-MIB::s5ChasComIpv6NetMask.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.45.1.6.3.3.1.1.21.1 s <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> s5ChasComIpv6NetMask.1
