Brandnew J9850A 5406R Switch stops routing after some time.
Hi,
i have a problem with a brandnew 5406R zl2 Switch. Our core switch is a DXS-3326GSR from D-Link. The core switch provides the transport VLAN for this Switch untagged. One other VLAN are provided tagged. It is a trunked uplink via LACP:
Here is my confguration:

This configuration works fine after a reboot. In the Client Net 10.76.97.0/24 I'm getting an IP from DHCP and I can acces the whole network.:
ping 192.168.1.18 source 560
192.168.1.18 is alive, time = 1 ms
But after a irregular period of time (30 min - 12 hours) the switch stops routing from the client Vlan 560.
ping 192.168.1.18 source 560
Request timed out.
I' ve tried a lot to get this device working properly, but this Problem presists. The shown ip routing table is correct:
Destination Gateway VLAN Type Sub-Type Metric Dist.
------------------ --------------- ---- --------- ---------- ---------- -----
0.0.0.0/0 10.76.33.5 550 static 1 1
10.76.33.4/30 tn**** 550 connected 1 0
10.76.97.0/24 cn**** 560 connected 1 0
127.0.0.0/8 reject static 0 0
127.0.0.1/32 lo0 connected 1 0
192.168.1.0/24 server**** 23 connected 1 0
The clients get IP from DHCP but are not able to access someting. If the switch is in this non working status the only thing you can do to get it working again is a reboot. Then the switch will work for some time.
sincerely
Eric

Re: Brandnew J9850A 5406R Switch stops routing after some time.
Is the host addressed as 192.168.1.18 patched to one of the untagged ports (D13-D20) on the 5400 that are in VLAN 23?
What is 192.168.1.18's default gateway set as?
What is connected to "Trk1"?
Why are you routing on the 5400 when you say your Dell switch is your "Core"?
If you have two switches doing routing, why are trunking VLANs between them?
When it is in a non-working state, show us a route print from the 192.168.1.18 host as well as from the Dell "Core".

Re: Brandnew J9850A 5406R Switch stops routing after some time.
Hi Vince,
thanks for your reply. I think i have to wait now, but i think the Problem is located in the D-Link Core Switch. I have changed the port at the core switch and now the problems don't show up.
