Network Access, Interswitch Connectivity and CDP
Karten in diesem Stapel (22)
- 1Describe MAC learning and aging.Learned MAC addresses are deleted after the age out value. When a switch encounters a MAC address that is not yet in it's table, it adds it.
- 2What is the default time of the age out value?300-600 seconds, depending on the number of MAC addresses learned.
- 3What does LAG stand for?Link Aggregation Group
- 4Describe frame switching.Frame switching is the act of sending a frame to the appropriate port(s) based on the destination address.
- 5What is the function of a broadcast address?A broadcast address sends information to every host on the network.
- 6What kind of port is used when connecting a VoIP phone?A voice and data access port.
- 7What is it called when a switchport is configured for both the voice and data vlans?This port is called a Multi-VLAN Access Port. (MVAP)
- 8Why does a VoIP phone have to be configured on both voice and data vlans?Because a VoIP phone has two ports, on for data and one for voice.
- 9What are the commands to configure a port for a VoIP phone (including verification)?"show run"
"conf t"
"int (interface)"
"switchport mode access"
"switchport mode access vlan (#)"
"switchport voice vlan (#)"
"end" - 10What does the term 'connectivity' refer to?The process of routing between VLANs.
- 11What is the purpose of a switch (dictionary definition)?The purpose of a switch is to facilitate communication within networks.
- 12What is 802.1Q?The networking standard that supports VLANs on an IEEE 802.3 (ethernet) network. Defines a system of VLAN tagging for frames.
- 13What is the Native VLAN?All untagged traffic is passed through the Native VLAN. This is how untagged traffic passes between switches. The Native VLAN applies to trunk ports, and data will be sent a receive via this VLAN.
- 14Describe CDP (what it is, what layer it runs on).Cisco Discovery Protocol is a layer 2 Cisco proprietary protocol that sends out periodic updates to a multicast address in order to make the device known, discover neighbors, and collect as much information as possible about other devices on the network.
- 15What does MIB stand for?Management Information Database.
- 16What happens when you use SNMP with CDP-MIB.Using SNMP with CDP-MIB allows network management applications to learn the device type and SNMP agent address of neighboring devices, and to send SNMP queries to those devices.
- 17What happens when you disable CDP after learning information about other devices on the network?The learned information will still be there until it times out.
- 18State the commands to disable, dispel of timers and hold times, and disable CDP on a port."no cpd run"
"no cdp enable"
"no cdp hold time"
"no cdp timer"
"no cdp source-(interface) vlan (#)" - 19State the commands used to enable, and verify CDP."show cdp"
"cdp run"
"show cdp neighbors"
"show cdp entry"
"show running-config (interface)" - 20What does the "show cdp neighbors" command show?Type of device discovered, name of the device, number and type of port, the number of seconds the CDP advertisement is valid for the port, device product number, and the port ID.
- 21What commands can be used to show more detail regarding CDP?"show cdp neighbors detail"
"show cdp entry"
"show cdp entry (device id)" - 22You cannot enable or disable CDP without this command;"cdp run"
