To make it possible to connect a LAG to different physical switches is to combine more than one physical switch into one logical switch using switch stacking techniques where the different physical boxes are seen as one logical switch for management and (spanning-tree) topology. The switches running in a stacked configuration always have to run ...
The PowerConnect 5500 series switches are gigabit Ethernet access-switches, available in 4 models: either a 24 or 48 port gigabit Ethernet switch or a 24/48 port gigabit Ethernet switch with Power-over-Ethernet option. Regardless of the model, the switches offer two HDMI ports for stacking and two SFP+ 10Gbit transceiver ports for 10Gb uplinks ...
The iKVM switch in the Dell enclosure is an Avocent switch and one can connect (tier) the iKVM module to other digital KVM switches such as the Dell 2161 and 4161 or Avocent DSR digital switches. Also tiering the iKVM to analog KVM switches as the Dell 2160AS or 180AS or other Avocent (compatible) KVM switches is possible. [2]
Switch A is replaced by two chassis, switches A 1 and A 2. They communicate between themselves using a proprietary protocol and are thereby able to masquerade as a single "virtual" switch A running a shared instance of LACP. Switch B is not aware that it is connected to more than one chassis. Switch B is also replaced by two chassis B 1 and B 2 ...
An alternative solution, introduced by many of the network manufacturers in the early 1990s, is to use link aggregation to combine two physical Ethernet links into one logical link. Most of these early solutions required manual configuration and identical equipment on both sides of the connection.
This page is about the legacy Dell PowerConnect switches that are no longer for sale. For the current portfolio please see the Dell Networking page.. All Dell switches will be rebranded to Dell Networking and will then have a different naming system based on a letter and a four-digit number.

Stacking resiliency. Multiple switches can have ways to bypass a “down” switch in a stack, thus allowing the remaining units to function as a stack even with a failed or removed unit. Layer 3 redundancy. Some stackable architectures allow for continued Layer 3 routing if there is a “down” switch in a stack.
