15 vlan limit on a Cisco 3800 router ??
Hi,
I have had a bizzare error saying that a Cisco 3800 series router has a 15 vlan limit.
Is this true ?
#sho vtp stat
VTP Version : 2

Maximum VLANs supported locally : 52
Number of existing VLANs : 19
VTP Operating Mode : Transparent

EdgeA#conf term
Enter configuration commands, one per line. End with CNTL/Z.
(config)#vlan 120
Vlan can not be added. Maximum number of 15 vlan(s) in the database.

or if you want to give more VLAN I advise to use subinterfaces:
int giga 0/0.1
encapsulation dot1q 1 native
.
.
.
.
and it gives you more vlan....
int giga 0/0.1
encapsulation dot1q 1 native
.

and it gives you more vlan....

Sub interfaces are sub interfaces off the trunk interface ??
sub interface of gigabit motherboard port.....

Hi,
Ahhh. Ok I have not done sub interfaces before so I am a little unsure. If I have a router which has two interfaces, each configured as trunks and each with vlan 101 on them.
Does this mean I need a sub interface on both with IP addresses on both ?
With the interface vlan I need only one interface definition, ie, one IP address.
Thanks
