What is interface bundle?
The Link Bundling feature allows you to group multiple point-to-point links together into one logical link and provide higher bidirectional bandwidth, redundancy, and load balancing between two routers. A virtual interface is assigned to the bundled link.
What is Ethernet bundle?
Bundle-Ethernet is the interface used for bundling Ethernet interfaces at the ASR9K platform. Each bundle can have at minimum one link and maximum of 64 links. Each bundle has one MAC address, one IP address and these QoS and ACL configuration for all the member links.
How do I setup a bundle interface?
To configure VLAN bundles, complete the following configurations: • Create a bundle instance. Create a VLAN interface (bundle sub-interface). Map the physical interface(s) to the bundle. For a VLAN bundle to be active, you must perform the same configuration on both end points of the VLAN bundle.
What is the difference between port channel and EtherChannel?
EtherChannel terminologies Spanning Tree Protocol – Is a data link layer protocol that prevents loops in networks with redundant links. Port-Channel – This refers to communication links between switches that combine multiple ethernet ports bandwidth into a single logical link.
What is port channel in switch?
A port channel is a communication link between two switches supported by matching channel group interfaces on each switch. A port channel is also referred to as a Link Aggregation Group (LAG). Port channels combine the bandwidth of multiple Ethernet ports into a single logical link.
What is EtherChannel and port channel?
EtherChannel is a port link aggregation technology or port-channel architecture used primarily on Cisco switches. It allows grouping of several physical Ethernet links to create one logical Ethernet link for the purpose of providing fault-tolerance and high-speed links between switches, routers and servers.
What is Po1 in Cisco switch?
PO1 is the etherchannel interface – Port channel interface. You can use Po1 interface as Layer 2 or Layer 3 interface incase of L3 you can assign IP to Po1 interface.
What is the difference between EtherChannel and port channel?
How many ports we can Bundled in EtherChannel?
Each EtherChannel can consist of up to eight compatibly configured Ethernet ports. All ports in each EtherChannel must be configured as either Layer 2 or Layer 3 ports. The number of EtherChannels is limited to 48.
What is LACP Cisco?
(LACP) LACP is defined in IEEE 802.3ad standard and enables Cisco switches to manage Ethernet channels between switches that conform to the standard. LACP facilitatesthe automaticcreation of EtherChannelsby exchanging LACP packets between Ethernet ports.
What is supernet and subnet?
Subnetting is the procedure to divide the network into sub-networks or small networks. Supernetting: Supernetting is the procedure to combine the small networks into larger space. In subnetting, Network addresses’s bits are increased. on the other hand, in supernetting, Host addresses’s bits are increased.
How many interfaces are in port-channel?
A port-channel bundles up to four individual interfaces into a group to provide increased bandwidth and redundancy. Port-channeling also load balances traffic across these physical interfaces.
