Features and Compatible Characteristics of Ethernet Link
Bundles
This list describes the properties and limitations of ethernet link bundles:
• Cisco NCS5500 Series Router supports mixed speed bundles. Mixed speed bundles allow member links
• The weight of each bundle member is the ratio of its bandwidth to the lowest bandwidth member. Total
• Any type of Ethernet interfaces can be bundled, with or without the use of LACP (Link Aggregation
• A single router can support a maximum of 63 bundle interfaces. Link bundles of only physical interfaces
• Physical layer and link layer configuration are performed on individual member links of a bundle.
• Configuration of network layer protocols and higher layer applications is performed on the bundle itself.
• IPv4 and IPv6 addressing is supported on ethernet link bundles.
• A bundle can be administratively enabled or disabled.
• Each individual link within a bundle can be administratively enabled or disabled.
• Ethernet link bundles are created in the same way as Ethernet channels, where the user enters the same
• The MAC address that is set on the bundle becomes the MAC address of the links within that bundle.
• Load balancing (the distribution of data between member links) is done by flow instead of by packet.
• QoS is supported and is applied proportionally on each bundle member.
• All links within a single bundle must terminate on the same two systems.
• Bundled interfaces are point-to-point.
• A link must be in the up state before it can be in distributing state in a bundle.
• Only physical links can be bundle members.

of different bandwidth to be configured as active members in a single bundle. The ratio of the bandwidth
for bundle members must not exceed 10. Also, the total weight of the bundle must not exceed 64. For
example, 100Gbps link and 10Gbps links can be active members in a bundle and load-balancing on
member links is based on bandwidth weightage.
weight of the bundle is the sum of weights or relative bandwidth of each bundle member. Since the
weight for a bundle member is greater than or equal to 1 and less than or equal to 10, the total member
of links in a bundle is less than 64 in mixed bundle case.

configuration on both end systems.
Data is distributed to a link in proportion to the bandwidth of the link in relation to its bundle.
