i have a FESX-424-PREM as a L3 BGP border ( only default route + my network announce, nothing special), and i cant add an a VLAN to tagged ports that re already have some vlans, after im trying to add some unused port its look ok, but when i try to add this vlan to port that already configured and alive - its fail whith no err message, in logs there is a record that a vlan have been deleted from console session:
SSH@border-ba1(config)#vlan 4015 name pantel_test by port
SSH@border-ba1(config-vlan-4015)#tagged ethernet 20 <<<<< port 20 isnt used, here vlan goes ok
Added tagged port(s) ethe 20 to port-vlan 4015.
SSH@border-ba1(config-vlan-4015)#tagged ethernet 5 <<<<<< port 5 and 7 have some tagged vlans, but i cant add next tagged vlan to it
SSH@border-ba1(config-vlan-4015)#tagged ethernet 7

sh run is in attachement, i've try different VLAN numbers, different ports - result is the same, on unused port its fine but on used port its removing complete vlan definition that i want to add as tagged vlan on port...

This looks like you doing the correct commands. The only thing I can think of is since you have turned off flow-control on port 5 and 7 that may have something to do with it.
Please redo your test of adding port 20 to VLAN 4015 BUT disabled flow-control on port 20 first. Let me know the results.

thanks alot for fast response, i've try it - on not connected/not used port its not depend on flow-control mode:
telnet@border-ba1(config)#interface ethernet 20
telnet@border-ba1(config)#vlan 4015 name pantel_test by port
telnet@border-ba1(config)#sh vlan 4015
Total PORT-VLAN entries: 9
Maximum PORT-VLAN entries: 4095
PORT-VLAN 4015, Name pantel_test, Priority level0, Spanning tree Off
Untagged Ports: None
Tagged Ports: 20
Uplink Ports: None
DualMode Ports: None

It was a long shot anyway Flow-control should have nothing to do with it.
Ok for changing system-max value, without a reboot, this is more like the couse I would think. I highly recommend you do the reboot as soon as you can..
One for test. try using vlan number < 32 (I cannot remmeber what the default no of vlan was on that box).

I have try a VLAN 28 - whith the same result. I will schedule reboot to 03:00 AM tonight, its a production border so unfortunately i cant do it now. I will let you know the result tomorrow morning.
Thanks alot for help.

im sorry for late response - i've been out of office for a two days. So - result of reload is strange. After planned reload the state have been the same. As you can see - i have changed some system-max parameters for pure ipv4 routing and vlan switching tuning, it seems that i have bad combination of values, because when i have removed all system-max settings and reload the switch - problem is gone. So i have a question - how can i set correctly system-max parameters when i need no ipx or multicast traffic on switch, and when i need as large as possible capacity of routing table and vlans number?
Thanks alot for help.

No problems with the delay mate, these I have used before;
system-max ip-route 128000

Ok, ill try it as soon as possible, but its a production box, so i will notify you about result when it will be done. BTW - where i can get an SNMP MIB base for this switch? i cant find it in download section...
