what is pvst in networking?

Per-VLAN Spanning Tree (PVST) maintains a spanning tree instance for each VLAN configured in the network. It uses ISL Trunking and allows a VLAN trunk to be forwarding for some VLANs while blocking for other VLANs.

The Cisco Catalyst 6500 Series Virtual Switching System (VSS) allows the clustering of two or more physical chassis together into a single, logical entity. This technology allows for enhancements in all areas of network design, including high availability, scalability, management, and maintenance.

A virtual circuit network uses a fixed path for a particular session, after which it breaks the connection and another path has to be set up for the next the next session. A Datagram based network is a true packet switched network. ... Packets reach in order to the destination as data follows the same path.

The vManage NMS is a centralized network management system that provides a GUI interface to easily monitor, configure, and maintain all Viptela devices and links in the overlay network. The vManage NMS software runs on a server in the network.

Public networks offer two types of virtual circuit--permanent and switched. Typically a subscription consists of a mixture of the two. A permanent virtual circuit (PVC) is a permanent association between two DTEs that is established when a user subscribes to a public network.

Trunking is for connecting two switches together (or a VMware chassis to a switch) so packets from multiple VLANs can cross over the "trunk." LACP is a protocol that is used to negotiate port channels (grouping multiple ports to multiply bandwidth). You're just teaming two NICs.

MPLS can encapsulate packets of various network protocols, hence the "multiprotocol" reference on its name. MPLS supports a range of access technologies, including T1/E1, ATM, Frame Relay, and DSL.

A fixed-length subnet mask (FLSM) is a sequence of numbers of unchanging length that streamlines packet routing within the subnets of a proprietary network. A subnet can be a geographically defined local area network (LAN).

The htons function takes a 16-bit number in host byte order and returns a 16-bit number in network byte order used in TCP/IP networks (the AF_INET or AF_INET6 address family). The htons function can be used to convert an IP port number in host byte order to the IP port number in network byte order.

vmstat (virtual memory statistics) is a valuable monitoring utility, which also provides information about block IO and CPU activity in addition to memory. vmstat provides a number of values and will typically be called using two numerical parameters. ... Procs r: The number of processes waiting for run time.

Network functions virtualization (NFV) is a way to virtualize network services, such as routers, firewalls, and load balancers, that have traditionally been run on proprietary hardware.

The labels identify virtual links (paths) between distant nodes rather than endpoints. MPLS can encapsulate packets of various network protocols, hence the "multiprotocol" reference on its name. MPLS supports a range of access technologies, including T1/E1, ATM, Frame Relay, and DSL.

A value-added network (VAN) is a third-party business that provides networking services for a fee. Networks facilitate communications among users and allow users to share resources with other users. Some examples of resources are data, information, hardware, and software.

Stream Control Transmission Protocol (SCTP) is a relatively new transport layer in the IP Protocol Stack. In an LTE network, SCTP is used to provide guaranteed message delivery between the MME and eNodeB. ... SCTP allows multiple message streams to be exchanged on a single SCTP connection.

['Primary VLAN - it forwards the traffic from the promiscuous ports to isolated ports, community ports and other promiscuous ports in the same private VLAN. ... ', 'Community VLAN - is a secondary VLAN. ... ', 'Isolated VLAN - is a secondary VLAN.']
249454
A Trunk is a link that carries traffic in multiple VLANs (this is a term that is used in 802.1Q but is not formally defined. ... That one allowed VLAN is called the native VLAN. So, “native VLAN” is not the same as PVID, although it could be partially implemented using PVID.

Telnet is a protocol that allows you to connect to remote computers (called hosts) over a TCP/IP network (such as the internet). Using telnet client software on your computer, you can make a connection to a telnet server (that is, the remote host).
