Hello,
Thanks for the rapid answer.
No, i can not ping the interface on the VLAN 31.
My phisic infrastructure is very simple:
3600 GE1/1 ------- wire ------- Firewall
(there is nothing in the middle)
On GE1/1 is configurated the VLAN 31, same thing on the interface of the Firewall (eth7=physic interface; eth7.31=VLAN31)
The strange thing is that my packets arive on the physic interface eth7 and not on the eth7.31
ex:
tcpdump -n -i eth7
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth7, link-type EN10MB (Ethernet), capture size 96 bytes
16:43:24.898633 arp who-has 10.31.0.240 tell 10.31.0.213
16:43:24.928618 arp who-has 10.31.0.240 tell 10.31.0.229
16:43:25.618190 arp who-has 10.31.0.240 tell 10.31.0.229
Using wireshark i also checked that the VLAN ID is missing, so the problem should be on the controller.
