What else can I help you with?
When you configure 802.1Q trunks on catalysts switches which limitation is imposed?
you must ensure a loop free topology before disabling the spanning-tree protocol you must configure the same native VLAN on both ends of the trunk link
Can STP be configured on an HP server?
Configuring Standard STP Parameters STP is disabled by default on Routing Switches. By default, each port-based VLAN on an HP device runs a separate spanning tree (a separate instance of STP). An HP device has one port-based VLAN (VLAN 1) by default that contains all the device's ports.
What is a STP and VTP?
STP stands for Spanning Tree Protocol, which is used to prevent loops in a network by blocking redundant paths. VTP stands for VLAN Trunking Protocol, which is used to manage VLAN configurations across a network by automatically synchronizing VLAN information. Both protocols help in optimizing network performance and ensuring network reliability.
What additional information is contained in the 12-bit extended system ID of a BPDU?
The 12-bit extended system ID in a Bridge Protocol Data Unit (BPDU) contains information about the VLAN (Virtual Local Area Network) associated with the bridge or switch. This extended system ID allows for the identification of the VLAN in which the BPDU is being transmitted, facilitating the proper functioning of Spanning Tree Protocol (STP) in environments with multiple VLANs. By incorporating the VLAN ID, the extended system ID helps manage traffic and prevent loops within VLANs effectively.
What does VTP mean in networking terms?
Vlan trunk Protocol
Which statements is correct concerning the default configuration of a new switch?
In the default configuration of a new switch, the switch operates in "out-of-the-box" mode, meaning all ports are set to access mode and belong to the default VLAN (VLAN 1). Spanning Tree Protocol (STP) is enabled by default to prevent loops in the network. Additionally, there is no password set for console, VTY, or enable access, and no IP address is assigned to the switch interfaces until configured by the user.
What is virtual trunking protocol VTP?
Virtual Trunking Protocol (VTP) is a Cisco proprietary protocol used in switched networks to manage VLAN configurations across multiple switches. It allows switches to share VLAN information, ensuring consistency in VLAN configuration throughout the network. VTP reduces the need for manual VLAN configuration on each switch, thereby simplifying network management and reducing the risk of errors. It operates in different modes, including server, client, and transparent, each with specific roles in VLAN information dissemination.
What is the spanning-tree network diameter on a cisco switch?
The default value for network diameter on a STP configuration is 7 (seven). This value can be changed, using the command: Switch(config)#spanning-tree vlan 1 root primary diameter 5 This command changes the network diameter 50 5 (five) hops from end to end
When the show spanning-tree vlan 33 command is issued on a switch three ports are shown in the forwarding state In which two port roles could these interfaces function while in the forwarding state?
designated and root
What switch features are typically used with Voice Over Internet Protocol?
VLAN and PoE are used
What could prevent etherchannels from forming?
EtherChannels may fail to form due to mismatched configurations between the participating interfaces, such as differing VLAN settings, speed, or duplex settings. Additionally, if there are inconsistent spanning tree configurations or if the interfaces are not in the same VLAN, the EtherChannel will not establish. Lastly, if any of the interfaces are in an error-disabled state or are not operational, this could also prevent the EtherChannel from forming.
What does VLAN stand for?
A VLAN is a virtual LAN. In technical terms, a VLAN is a broadcast domain created by switches. Normally, it is a router creating that broadcast domain. With VLANs, a switch can create the broadcast domain. This works by, you, the administrator, putting some switch ports in a VLAN other than 1, the default VLAN. All ports in a single VLAN are in a single broadcast domain. Because switches can talk to each other, some ports on switch A can be in VLAN 10 and other ports on switch B can be in VLAN 10. Broadcasts between these devices will not be seen on any other port in any other VLAN, other than 10. However, these devices can all communicate because they are on the same VLAN. Without additional configuration, they would not be able to communicate with any other devices, not in their VLAN.
