Hello
I've met next problem.
There is router under freebsd with nge card as parent for several vlans.
vlan102: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.0.4.1 netmask 0xfffffe00 broadcast 10.0.5.255
ether 00:40:f4:47:be:10
media: Ethernet autoselect (1000baseSX <full-duplex>)
status: active
vlan: 102 parent interface: nge0
Under 5.4 vlan + nge doesn't work - core dumps
but with 3 diffs from HEAD 1.70-1.72 for if_nge.c - all is working.
Under 6 - it doen's work - but i've tried after Brooks Davis commits.
It looks next:
1) vlan sends packets, but do not receive
netstat -i shows 0 for ipackets field
2) tcpdump for parent interface shows nothing , but other side sees this arp
tcpdump -n -i nge0 vlan 102 - shows nothing except outgoing "arp who has"
3)i've met same problem for lnc card under vmware
I've saw in freebsd-net notes about linux-freebsd connectivity problems
for dot1q
It possible same problem here.
Also i've checked same configuration for rl and em cards - they works well.
My question:
How can i debug this situation ?
I've looked through if_rl, if_lnc and if_nge diffs as befor so after
brooks@ patches
- nothig special.
Jura
