decAtmKeyswitchPosition

Module: DEC-ATM-CHASSIS-MIB

OID (symbolic): DEC-ATM-CHASSIS-MIB::decAtmKeyswitchPosition

OID (numeric): 1.3.6.1.4.1.36.2.18.30.1.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: Indicates the position of the keyswitch. The keyswitch position determines the type of access allowed to network management and to out-of-band management. For SNMP access, 'secure' means no SNMP access. 'Local' means read-only SNMP access. Other values allow read- write SNMP access. Access is still subject to community string, IP address, and privileged port restrictions. Now that I think about it, the 'secure' value (which was copied from GIGAswitch/FDDI) is silly. If the keyswitch is in that position, you will not be able to read object (unless SNMP makes a special exception).

What is decAtmKeyswitchPosition?

Reports the physical keyswitch position on the chassis, which gates the level of SNMP access allowed: 'secure' blocks SNMP entirely, 'local' permits only read-only access, and other positions allow read-write access (still subject to community string and IP restrictions). If SET operations to the switch keep failing, check this object first, since a 'secure' or 'local' keyswitch position — not a permissions bug — may be the real cause.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.36.2.18.30.1.1.2
snmpwalk -v2c -c public <target> DEC-ATM-CHASSIS-MIB::decAtmKeyswitchPosition

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.36.2.18.30.1.1.2.1
snmpget -v2c -c public <target> DEC-ATM-CHASSIS-MIB::decAtmKeyswitchPosition.1
