chasControlImageSuffix

Module: CHASSIS-MIB

OID (symbolic): CHASSIS-MIB::chasControlImageSuffix

OID (numeric): 1.3.6.1.4.1.800.2.1.3.1.1.17

Node type: OBJECT-TYPE

Type: DisplayString

Access: read-write

Description: This character string will be used to determine which file is downloaded to the NIs to be brought up by the chassis manager. Only files with suffixes (the part of the file name following '.') matching this character string will be downloaded to NIs which are inserted into the chassis or reset. If the chassis is rebooted these files will be used for the initial NI loads. This value can only be set on the Primary MPM. If automatic synchronization is enabled and the required image files on the Secondary match those on the Primary (State is Redundant or CONFIG FB) then the value set will be copied to the Secondary after the first 5min period of no configuration updates or when a configsync is envoked.

What is chasControlImageSuffix?

This object holds a file-suffix string that determines which firmware image files get downloaded to network interface modules when they're inserted, reset, or when the chassis itself reboots. An admin managing multiple firmware image variants on the flash file system uses this to control exactly which image family gets pushed to NIs, preventing an incompatible or wrong-version image from loading onto a card at boot. Setting chasControlImageSuffix to b62 would ensure only files ending in .b62 get loaded onto NI modules when inserted or the chassis reboots, ignoring other image files present on flash.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.800.2.1.3.1.1.17
snmpwalk -v2c -c public <target> CHASSIS-MIB::chasControlImageSuffix

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.800.2.1.3.1.1.17.1
snmpget -v2c -c public <target> CHASSIS-MIB::chasControlImageSuffix.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.800.2.1.3.1.1.17.1 s <value>
