White Paper

vss(config)#port-channel hash-distribution ?

adaptive selective distribution of the bndl_hash among port-channel members

fixed distribution of the bndl_hash among port-channel members

vss(config)#int port-channel 4

vss(config-if)#port-channel port hash-distribution ?

adaptive selective distribution of the bndl_hash among port-channel members

fixed fixed distribution of the bndl_hash among port-channel members

The algorithm selected with these commands is applied only at the next hash-distribution instance, which usually

occurs on a port-channel member link transition event.

Last applied Hash Distribution Algorithm: Adaptive

Although this new load-distribution algorithm requires configuration for regular Cisco EtherChannel and multichassis

Cisco EtherChannel interfaces, it is the default load-distribution algorithm used on the virtual switch links.

Multichassis Cisco EtherChannel Links

The multichassis Cisco EtherChannel interface spans more than a single physical switch (Figure 12). Cisco Virtual

Switching System allows for the formation of this multichassis Cisco EtherChannel link and allows all the dual-homed

connections to and from the upstream and downstream devices to be configured as Cisco EtherChannel links, as

opposed to individual links. As a result, multichassis Cisco EtherChannel links allow for implementation of new

network designs where true Layer 2 multipathing can be implemented without the reliance on Layer 2 redundancy

protocols such as Spanning Tree Protocol. With 12.2(33)SXI and above, VSS supports 512 etherchannels.
