This document describes how the IEEE 8. Link Bundling feature leverages the Ether. Channel infrastructure within Cisco IOS software to manage the bundling of various links. Also described are network traffic load- balancing features to help minimize network disruption that results when a port is added or deleted from a link bundle.

For the latest feature information and caveats, see the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the . Wysiwyg Web Builder Serial Keygen Download Crack.

Channel bundles individual Gigabit Ethernet links into a single logical link that provides the aggregate bandwidth of up to eight physical links. All LAN ports in each Ether.

Channel must be the same speed and all must be configured either as Layer 2 or as Layer 3 LAN ports. Inbound broadcast and multicast packets on one link in an Ether. Channel are blocked from returning on any other link in the Ether. Channel. Also when a failure occurs, a trap is sent that identifies the device, the Ether. Channel, and the failed link. The configuration of a port channel interface affects all LAN ports assigned to that port channel interface. Any configuration or attribute changes you make to the port channel interface are propagated to all interfaces within the same channel group as the port channel; that is, configuration changes are propagated to the physical interfaces that are not part of the port channel but are part of the channel group.

This feature helps improve the cost effectiveness of a device by increasing cumulative bandwidth without necessarily requiring hardware upgrades. In addition, IEEE 8. Link Bundling provides a capability to dynamically provision, manage, and monitor various aggregated links and enables interoperability between various Cisco devices and devices of third- party vendors.

LACP packets are exchanged only between ports in passive and active modes. The protocol . After LACP identifies correctly matched Ethernet links, it facilitates grouping the links into an Ether.

Channel. Then the Ether. Channel is added to the spanning tree as a single bridge port. The system priority can be configured automatically or through the command- line interface (CLI). LACP uses the system priority with the device MAC address to form the system ID and also during negotiation with other systems. The port priority can be configured automatically or through the CLI. LACP uses the port priority to decide which ports should be put in standby mode when there is a hardware limitation that prevents all compatible ports from aggregating.

LACP also uses the port priority with the port number to form the port identifier. The administrative key defines the ability of a port to aggregate with other ports. A port's ability to aggregate with other ports is determined by the following: –Port physical characteristics such as data rate, duplex capability, and point- to- point or shared medium –Configuration restrictions that you establish LACP, on ports configured to use it, tries to configure the maximum number of compatible ports in an Ether. Channel, up to the maximum allowed by the hardware. In Cisco IOS Release 1. SB2 on the Cisco 1.

LACP. To use the hot standby feature in the event a channel port fails, both ends of the LACP bundle must support the lacp max- bundle command. Operations, administration, and maintenance (OAM) packets also use the Slow Protocol link type. Subsequently, a subtype field is defined per the IEEE 8. During the switchover, the port channel is maintained in the LINK.

In the port channel interface, a configurable option is provided to bring down the port channel interface when the number of active links falls below the minimum threshold. For the port- channel state to be symmetric on both sides of the channel, the peer must also be running LACP and have the same lacp min- bundle command setting. The selected mode applies to all Ether. Channels configured on the device.

Ether. Channel load balancing can also use Multiprotocol Label Switching (MPLS) Layer 2 information. When a port is added to an Ether. Channel or an active port fails, the load balance bits are reset and reassigned for all ports within that Ether. Channel and reprogrammed into the ASIC for each port.

This reset causes packet loss during the time the reassignment and reprogramming is taking place. The greater the port bandwidth, the greater the packet loss. On the Cisco 7. 60. A hot standby port is bundled in (swapped into) an aggregation when a previously active port fails. When the swapped- in port is bundled, the stored load share of the failed port is assigned to the swapped- in port. The remaining ports in the bundle are not affected.

If a second failure occurs before the first failure recovers, the load share bits for member links are recomputed. When a failed (unbundled) port is detected and is the first failure, its load share is stored.

When a hot- standby port is identified and is bundled in, it takes the load share bits of the previously failed port. If the failed port comes back up, it replaces the hot- standby port in the bundle and the load share bits are transferred back to the original port.

With this fixed algorithm, the load share bits are assigned sequentially to each port in the bundle. Consequently, the load share bits for existing ports change when a member link joins or leaves the bundle. When these values are programmed in the ASIC, substantial traffic disruption and, in some cases, duplication of traffic can occur. This algorithm uses a port reassignment scheme that enhances Ether. Channel availability by limiting the load distribution reassignment to the port that is added or deleted.

The new load on existing bundled ports does not conflict with the load programmed on those ports when a port is added or deleted.
