Hello, the 2950 needs the newest code to support more then 64 vlans in spanning-tree (PVST). With the new code you'll get 128 vlans support as well as extended vlan range support (in transparent mode) ... plus a whole lot of bug fixes as 12.1(19)EA1 is fairly buggy ... there is a nasty SNMP bug that chews up flash in that code.
Hope that helps.

Subject: Adding a vlan failed on Cisco2950
Dear All,
I have a problem with one of my switches (Cisco 2950) when
adding a new vlan on it
The following message appears when configuring new vlan
*POP-switch#conf t*
Enter configuration commands, one per line. End with CNTL/Z.
*POP-switch(config)#vlan 71*
POP-switch(config-vlan)#^Z
Proposed configuration has too many VLANs for this device's core memory
resources. Either reduce the number of VLANs proposed or use another
VTP
device to configure database. (The latter will cause this device to
enter
TRANSPARENT mode automatically if propagated to it.)
APPLY VLAN changes failed.
*POP-switch#sh vlan id 71
*VLAN id 71 not found in current VLAN database
Show memory gives that the Switch has a fee memory
*POP-switch#sh memory*
Head Total(b) Used(b) Free(b)

Processor 80BA6420 4803552 2315660 2487892 2359716

I/O A08C16E0 3034400 689092 2345308
2305068 2344440
I have only 65 active vlans on the switch
I tried to add the vlan using the vlan database but the same message
appears
too
I am using the following IOS image "*c2950-i6q4l2-mz.121-19.EA1c.bin*"
Any help on this behavior
Regards
