Figure 2-17. 10-GbE Aggregation Topology
The J8988A module in the Switch 5300xl Series will provide customers with a
10-GbE uplink connection (expected throughput is 2.5 to 7 Gbps, depending
on packet size).
Traffic from a single MAC SA to a single MAC DA cannot
exceed 1 Gbps. Each Switch 5300xl Series can support up to four J8988A
modules. The 10-GbE module supports trunking – however, each trunk will
support at most two 10-GbE ports, and 10-GbE ports cannot be mixed with
other port speeds in the trunk.
If more than two J8988A ports are added to an IEEE 802.3ad (LACP) dynamic
trunk the remaining ports beyond the first two, as per the LACP specification,
are placed in a "standby" mode. All four ports could be placed in a dynamic
trunk. Two ports will remain on "standby" and be blocked, and two ports will
be added to the dynamic trunk. If one (or both) of the ports in the dynamic
trunk are disabled or disconnected, the highest priority "standby" port(s) will
then be added to the trunk and the disabled/disconnected port(s) will be
removed from the trunk. This works just like 10/100/1000 ports.
