If you want to shutdown a port on a Cisco 2960 Catalyst Switch you will need to connect to the router (either SSH, TelNet or connect using the Console cable) and enter the interface you want to shutdown. You will then need to enter the shutdowncommand. An example is given below for Fast Ethernet 0/2
Router> enable
Router# configure terminal
Router(config)# interface fa0/2
Router(config-if)# shutdown

When port security is enabled a switch port uses the default violation mode of until specifically configured to use a different violation mode?
Yes, By default port security is disabled on a Cisco switch. If it is enabled the default violation mode is shutdown with a maximum MAC address count of 1. Even if port-security is enabled it will not place a port into the shutdown state until either MAC address sticky or a static MAC address is configured on the port.
What is 'err-disabled' error. it is frequently blocking the port of your cisco switch?
This is caused by port security being enabled and having the violation setting set to shutdown. This is triggered when you have two many MAC addresses listed for the port of if a BPDU is sent to that port, depending on how port security is configured.
Where is the ip address on a cisco switch for telnet?
The Cisco switches I have seen don't have an IP address by default. You have to connect to the switch with a console cable - one that connects to the console port on the switch, and to the serial port on the computer - and do some initial configuration, including the IP address.The Cisco switches I have seen don't have an IP address by default.

How many switch ports does a Cisco phone have?
Most Cisco phones act as a two-port switch, with one port facing the network and the other port for attaching a desktop device like a PC.
Which Cisco switch feature is used to limit the number of valid MAC addresses that a switch associates with a switchport?
port security
What are some features of Cisco SLM2024 24-port Gigabit Smart Switch?
The Cisco SLM2024 24-port Gigabit Smart Switch features 2 mini-GBIC converters, jumbo frame support, port level security, and MAC based-filtering. It also has 128 active VLANs.
What does the command no shutdown do on a Cisco device?
Enables the interface.
What is port security in cisco?
port security is a CLI command used to restrict access to a network from a cisco switch by allowing access only to the hosts whose MAC addresses are defined in the switch. except the allowed hosts remaining hosts will be blocked based on the violation mode chosen.
What is power Consumption of cisco 24 port switch?
That depends on the model of the switch, you can lookup the technical specs by doing a quick search at cisco.com.
How do you assign IP to cisco switch?
You can't assign an ip to a switch but you can add one to the interfaces......... like: for the management vlan (or any other vlan) Switch(config)#int vlan 1 Switch(config-if)#ip address {your ip address} {mask} Switch(config-if)#no shutdown any other port Switch(config)#int <fa, G, S> <interface number i.e. 0/0> Switch(config-if)#ip address {your ip address} {mask} Switch(config-if)#no shutdown and for a default gateway Switch#conf t Switch(config)#ip default-gateway {ip address}
Can I connect a Cisco catalyst 2950 switch to a hub?
Yes. A hub will be one giant collision domain for that entire switch port. So if its an 8 port hub and you have 8 devices connected to it that collision domain will have 8 devices in it.
What is the use of broadcast networks?
Broadcast Networks mainly used to send datas (information) through network switch(Ex: Cisco 2950) to all destinations which are connected the switchports except the sending port.
