Port channel scale and support for SLX 9740 and Extreme 8820 devices:

Table 1. Port-channel scale for SLX 9740/Extreme 8820 devices.
Device LAG Profile Supported port-channel IDs Maximum links per port-channel
SLX 9740-40/Extreme 8820-40 default 1-256; Only 77 portchannels may be created at any one time 64
SLX 9740-80/Extreme 8820-80 default Only 153 portchannels may be created at any one time. 64
Note

Note

  • For the 1U SLX 9740-40/Extreme 8820-40 devices, the number of LAGs will be 77, where:
    • 76 are the front end ports (all breakouts)
    • 1 (insight port)
  • For the 2U SLX 9740-80/Extreme 8820-80 devices, the number of LAGs will be 153. where:
    • 152 are the front end ports (all breakouts)
    • 1 (insight port)
(For SLX 9540 and SLX 9640 ) Maximum numbers of port-channel IDs and links per port-channel vary with device and LAG profile, as follows:

Examples

The following example associates interface 0/9 with port-channel 4 and activates LACP.

device# configure terminal
device(config)# interface ethernet 0/9 
device(conf-if-eth-0/9)# channel-group 4 mode active
