Replacing v12.1 FastE top-of-rack switches with v15.2 GigE

[efjadmin]

I'm replacing EOL 2960 FastE switches with 2960-X GigE. The old switches are configured with a trunk port uplink to the management network and accessed via the VLAN IP address. I have been unable to connect to the new switches when I try to configure them the same way. I also haven't had any luck connecting to the management port. Here's the running config for each:

interface FastEthernet0
ip address 10.128.3.3 255.255.255.128

interface GigabitEthernet1/0/1
description esw1 Uplink
switchport trunk native vlan 100
switchport mode trunk
switchport nonegotiate
srr-queue bandwidth share 1 30 35 5
priority-queue out
mls qos trust cos
macro description cisco-switch | cisco-switch | cisco-switch | cisco-switch
auto qos trust
spanning-tree link-type point-to-point

interface Vlan100
ip address 10.128.255.11 255.255.255.0
no ip route-cache

what is other side switch can you post the configuration of other switch side where this uplink connected.

Is the UPlnk port come up ? if so please post show interface X/X both the side.

clear IP arp table , since the device changed (worth doing it).

[Jaderson Pessoa]

from other side, could provide configuration?

is vlan 100 native too on other side?
Are vlan's allowed from trunk ports on both sides?

Thanks in advance.

Here's the port on the other side:

Can you explain more here :

original post you have mentioned "interface GigabitEthernet1/0/1"

Now recent one you have 1/0/3 and other end 1/0/24 ? - which one is correct ?

show post show vlan, show interface trunk. both the sides.

[efjadmin]

Sorry about the 1/0/24 output. 1/0/3 is the other end. Here's the 1/0/1 status:

I figured out the problem.

Though I had made sure the trunk ports and vlan interfaces were configured, I had failed to enable the vlan itself. I was able to connect after adding the following:

engdevrack(config)#vlan 100

engdevrack(config-vlan)#state active

engdevrack(config-vlan)#no shut
