Starting seeing these pop up periodically on an ISR 4351.
PLATFORM-4-ELEMENT_WARNING: SIP2: smand: RP/0: Used Memory value 89% exceeds warning level 88% Severity Level : 3
A simple reboot of the router lowered the platform memory in use and also stabilized it.
Install ansible. For example, on Ubuntu Linux:
sudo apt-get install ansible
Populate /etc/ansible/hosts
[myrouters] router1.mydomain.com router2.mydomain.com [myswitches] Switch1 Switch2.mydomain.com 192.168.1.1
Try a read-only command just on a single router
ansible router1.mydomain.com -u myusername -k -m raw -a "show version"
Try a command on a group of routers
ansible myrouters -u myusername -k -m raw -a "show version"
One important thing to understanding in IOS-XE is the different numbers that can be returned when checking CPU and memory statistics. There’s some very down in the weeds docs on this, but the simplest way to break it down is process vs. platform. Processes is essentially control plane, while platform is data plane.
CLI command: show processes cpu
SNMP OIDs:
1.3.6.1.4.1.9.2.1.56.0 = 5 second 1.3.6.1.4.1.9.2.1.57.0 = 1 minute 1.3.6.1.4.1.9.2.1.58.0 = 5 minute
CLI command: show processes cpu platform
SNMP OIDs:
1.3.6.1.4.1.9.9.109.1.1.1.1.3.7 = 5 second 1.3.6.1.4.1.9.9.109.1.1.1.1.4.7 = 1 minute 1.3.6.1.4.1.9.9.109.1.1.1.1.5.7 = 5 minute
Note – Most platforms will be multi-core.
CLI command: show processes memory
SNMP OIDs:
1.3.6.1.4.1.9.9.48.1.1.1.5.1 = Memory Used 1.3.6.1.4.1.9.9.48.1.1.1.6.1 = Memory Free
CLI command: show platform resources
SNMP OIDs:
1.3.6.1.4.1.9.9.109.1.1.1.1.12.7 = Memory Used 1.3.6.1.4.1.9.9.109.1.1.1.1.13.7 = Memory Free 1.3.6.1.4.1.9.9.109.1.1.1.1.27.7 = Memory Committed
