NEs fail to be added
1. Ping NEs from
eSight. It is found that the network connectivity is normal.
2. Check the SNMP configuration.
snmp-agent sys-info version v2c
snmp-agent mib-view included View_ALL iso
snmp-agent community read cipher ******* mib-view View_ALL acl
snmp-agent community write cipher ****** mib-view View_ALL acl
3. Check whether the ACL configuration is correct.
acl number 2005
rule 0 permit source 10.X.X.5 0
4. On the eSight, obtain packet header information about the SNMP reply packets
that are not received by NEs.
5. Check the route information on NEs. It is found the traffic hitting VPN
The interface is bound to a VPN instance, and the reply packets sent by
the NEs are transmitted through VPN.
VPN is used in the ACL rule.
rule 5 permit source 10.X.X.5 0 vpn-instance XXXX
