We bought a new SLM2048 for the new sales department in our organization, this need to be connected to the network to one of the core switch. We have to creat the new vlan for the new sales department say as vlan 8 on core with svi say 10.0.8.1 /24. after this I need to put the port gig2/32 on core switch in access vlan 8 and connect to the switch SLM2048 on port 1. First I changed the IP address of SLM2048 from default to 10.0.8.10 and then got access by changing my laptop Ip address to the same subnet 10.0.8.11 and able to get access then created the vlan 8 in slm2048 and tagged the port 1 to vlan 8. But as soon as I changed the management vlan from 1 to 8 it disconnects and am not able to ping the ip 10.0.8.10. Please suggest how to make slm2048 accessible to the network with the above requirement.
