Hi all,
I am investigating a BUG ID : CSCux68796 which is coused of high CPU utilization on ASR 1000 Series.
Symptom:
An IOS-XE based router running 3.13.6S-15.4(3)S6-, 3.16.2S-15.5(3)S2, or 3.17.1S-15.6(1)S1 may experience high CPU under the "SNMP" process when doing get-next to consistently get the value of "entStateStandby".
Conditions:
IOS-XE based router running 3.13.6S-15.4(3)S6-, 3.16.2S-15.5(3)S2, or 3.17.1S-15.6(1)S1
Customers should upgrade to either:
- 3.13.7S
- 3.16.3S
- 3.17.2S
Or later.
This issue has only been observed on Cisco ASR 1000 Series Aggregation Services Routers.
Affects devices configured with either SNMPv1, SNMPv2 or SNMPv3.
Workaround:
None.
what I don't understand here... it is saying ASR 1000 series running 3.13.6S, 3.16.2S, 3.17.1S might experience high CPU,
then older version could experience the same issue? is this related to vulnerability 'CVE-2017-3820' ??
