VPN Manager was not able to discover any traffic statistics for VPNs which were binded to vlan-interface; On the other hand it was able to discover traffic statistics for VPN’s binded to sub-interface.
This problem was discovered while configuring VPN Manager (NSM 2.20 VPN-0609SP07 installed on windows2000 server) to monitor vlan-interface traffic statistics on NE40E (VRP5.30-31002M03).
No Alarms found.
However, History data, Realtime Incoming and Outgoing traffics for Vlan interafces all were showing zeros.
To Upgrade the VRP version of NE40E to VRP5.30-31002W or higher.
The device NE40E was not capturing any traffic on vlan-interface it self:
display interface vlanif 223
Vlanif223 current state : UP
Line protocol current state : UP
The Maximum Transmit Unit is 1500 bytes
Internet Address is 192.168.230.33/28
IP Sending Frames' Format is PKTFMT_ETHNT_2, Hardware address is 00e0-fc87-109c
Physical is VLANIF
Last 5 minutes input rate 0 bytes/sec, 57 packets/sec
Last 5 minutes output rate 0 bytes/sec, 0 packets/sec
876 packets input, 0 bytes, 0 drops
0 packets output, 0 bytes, 0 drops
The input rate and output rate both of them shows 0 bytes/sec
The new release VRP5.30-31002W for NE40E and its following Versions have already provided this feature of supporting statistics on vlan interface.
Also we need to apply the command “enable statistics vlan-interface".
