cardRedundSlotMask
Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::cardRedundSlotMask
OID (numeric): 1.3.6.1.4.1.277.1.7.2.1.10
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: A 32-bit mask indicating the slot position of this card and its redundant partner. The low bit is slot 1 and the high bit is slot 32.
What is cardRedundSlotMask?
This is a 32-bit bitmask where each bit position corresponds to a chassis slot, with bit 0 representing slot 1 and bit 31 representing slot 32, and the bits for this card's own slot and its redundant partner's slot both set. Because it's read-write, misconfiguring this mask, for example setting a bit for a slot that isn't actually populated with the partner card, can silently break the redundancy pairing without any other alarm firing. For example, a card in slot 3 paired with its partner in slot 4 would show cardRedundSlotMask as 0x0000000C, and an admin decoding that value confirms the pairing matches the physical layout.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.7.2.1.10 snmpwalk -v2c -c public <target> CASCADE-MIB::cardRedundSlotMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.7.2.1.10.1 snmpget -v2c -c public <target> CASCADE-MIB::cardRedundSlotMask.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.7.2.1.10.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cardRedundSlotMask.1
