Hi
I try to use vlan with 2.4.19pre8-ac5 and 00:10.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 74) network card
I successfully setup vlan and got ping's (traffic) But only with small packets
At main interface all work good [root@watcher linux]# ping -s 1480 x.x.x.1 PING x.x.x.1 (x.x.x.1) from x.x.x.11 : 1480(1508) bytes of data. 1488 bytes from x.x.x.1: icmp_seq=1 ttl=255 time=6.93 ms 1488 bytes from x.x.x.1: icmp_seq=2 ttl=255 time=3.05 ms
--- x.x.x.1 ping statistics --- 2 packets transmitted, 2 received, 0% loss, time 1007ms rtt min/avg/max/mdev = 3.056/4.993/6.930/1.937 ms
Vlan interface [root@watcher linux]# ping -s 1480 x.x.x.242 PING x.x.x.242 (x.x.x.242) from x.x.x.244 : 1480(1508) bytes of data.
--- x.x.x.242 ping statistics --- 3 packets transmitted, 0 received, 100% loss, time 2017ms
Both pinged addresses in same subnet for approved interface And vlan is work [root@watcher linux]# ping -s 1400 x.x.x.242 PING x.x.x.242 (x.x.x.242) from x.x.x.244 : 1400(1428) bytes of data. 1408 bytes from x.x.x.242: icmp_seq=1 ttl=255 time=2.31 ms 1408 bytes from x.x.x.242: icmp_seq=2 ttl=255 time=1.79 ms
--- x.x.x.242 ping statistics --- 2 packets transmitted, 2 received, 0% loss, time 1010ms rtt min/avg/max/mdev = 1.794/2.056/2.319/0.266 ms
I'm try to search information about this trouble found such patch
# My 3C59X has MTU problems.
Edit the 3C59x.c, find the place where it says:
static const int mtu = 1500; and replace 1500 with static const int mtu = 1504;
but I got same trouble with this patch
