cseSysUpTime

Module: CISCO-SYSTEM-EXT-MIB

OID (symbolic): CISCO-SYSTEM-EXT-MIB::cseSysUpTime

OID (numeric): 1.3.6.1.4.1.9.9.305.1.1.10

Node type: OBJECT-TYPE

Type: TimeIntervalSec

Access: read-only

Description: The time (in seconds) since the entire system was last re-initialized as a result of reload. The initialization being system loaded and running with a system image software on the first active supervisor (SUP). In High Availibility (HA) capable system / System that provides Supervisor module redundancy, this uptime indicates time elapsed since the first active SUP was booted. This will not change even if the active SUP goes down and stand-by takes over as active.

What is cseSysUpTime?

Reports how many seconds have elapsed since the entire system (chassis) was last reloaded and came back up running its system software on the first active supervisor, useful for tracking uptime in high-availability setups.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.305.1.1.10
snmpwalk -v2c -c public <target> CISCO-SYSTEM-EXT-MIB::cseSysUpTime

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.305.1.1.10.1
snmpget -v2c -c public <target> CISCO-SYSTEM-EXT-MIB::cseSysUpTime.1

SNMPv3 example:

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