An IP addresses is needed on sc0 interface:

set interface sc0 1

where 1 after sc0 is the vlan number.

the set command is for catos devices. the other command would be like any other router... in config mode.

interface loopback #

ip adddress 192.168.x.x 255.255.x.x

no shutdown

We typically use Loopback 0 for management but you can use other numbers.

If the switch is running native IOS then you are in the RP and to manage the switch all you have to do is this. Configure a SVI aka vlan interface for the mgmt vlan and assign it an IP from the subnet.

int vlan (mgmt_vlan)

ip address x.x.x.x x.x.x.x



I assigned a loopback on both switches. for SW1

and for SW2

I cannot ping neither from the management PC @

The switch (where Management PC is )port says:


interface GigabitEthernet10/33


switchport mode access

no ip address


interface GigabitEthernet10/34


switchport mode access

no ip address


the loopback port says:


interface Loopback0

ip address


All ports show UP-UP yet I cannot ping them or access them via telnet from the management PC.

You have configured g10/33 & g10/44 to be part of vlan 1 and hence, you can configure like this;

int vlan 1

ip address (

I assume this subnet,, belongs to vlan 1 and if it's not then assign int vlan 1 an IP from that subnet. The devices connected to those two ports need to use the int vlan 1 IP as the default gateway.

Your management PC is connected to VLAN 1.

I suggest removing the IP from the loopback on the respective switches and assign them under interface vlan 1 and make sure to issue a 'no shutdown'.

Is IP routing enabled in the switch. Either way try adding this command 'ip routing' from the global config mode. Is the interface g10/33 or 10/34 up?

Please post the output from the following commands:

show ip int bri | ex una

show int status | i connected

show vlan | ex una
