1Gbe Uplink Recommendations - Dell PS4000 Configuration Manual

Some switch vendors have proprietary or enhanced link aggregation protocols. For example,
Cisco supports Port Aggregation Protocol (PAgP) that contains advanced management features.

Use LACP as method for link aggregation when I/O modules and external switches are from
different vendors
The industry standard link aggregation protocol is IEEE 802.3ad (802.1AX), also known as the
Link Aggregation Control Protocol (LACP). LACP is typically the only method for creating link
aggregation groups that can link switches from multiple vendors.

1GbE Uplink Recommendations

If 10GbE links are not available, 1GbE links can be used to link the blade enclosure I/O modules to the
external switch stack. Configurations using 1GbE uplinks should be limited to smaller installations
limited to one or two M1000e blade enclosures due to increased cabling complexity.
