Hi Amr,
AS per the below cisco link:-
Catalyst 2950 switches that run the standard software image (SI) support
64 VLANs; Catalyst 2950 and Catalyst 2955 switches that run the enhanced
software image (EI) support 250 VLANs. Refer to the release notes for
the list of switches that support each image. VLANs are identified with
a number from 1 to 4094 when the EI is installed and 1 to 1005 when the
SI is installed. VLAN IDs 1002 through 1005 are reserved for Token Ring
and FDDI VLANs. VTP only learns normal-range VLANs, with VLAN IDs 1 to
1005; VLAN IDs greater than 1005 are extended-range VLANs and are not
stored in the VLAN database. The switch must be in VTP transparent mode
when you create VLAN IDs from 1006 to 4094.

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*

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
