Terminal(PC) 1 is connected with sw1 .


PC1 ip is 10.129.113.44.

2900 series is a pure layer 2 switch.


Or you'll assign a port in the same vlan as the switch_management vlan


Or add a L3 capable device

If PC1 is in the same subnet/vlan as SW1 & SW2 management IP addresses then you can ping/telnet. If it is in a different subnet then you cannot do this without a L3 device to route between the 2 vlans.


As you don't give the subnet masks it is not possible to say for sure whether SW1/SW2 are in different vlans/subnets than PC1.

If your trying to reach the management of the sw's from PC1, that will not work, w/o layer 3, they are not in the same subnet.
