flooded to all ports of the relevant VLAN. MAC Multicast Support Multicast service is a limited Broadcast service that enables one-to-many and many-to-many connections for information distribution. In Layer 2 Multicast service, a single frame is addressed to a specific Multicast address, from which - Dell PowerConnect 5524P | User Guide - Page 19
by the device. When Layer 2 frames are forwarded, Broadcast and Multicast frames are flooded to all ports on the relevant VLAN. This occupies bandwidth, and loads all nodes connected on all ports.

to enhance VoIP service by configuring ports to carry IP voice traffic from IP phones on a specific VLAN. VoIP traffic has a preconfigured OUI prefix in the source MAC address. Network administrators can configure VLANs from which voice IP traffic is 20 Dell PowerConnect 55xx Systems User Guide - Dell PowerConnect 5524P | User Guide - Page 21
to automatically prevent and resolve Layer 2 forwarding loops. Switches exchange configuration messages using specifically-formatted frames, and selectively enable and disable forwarding on ports.

minimal operational impact in the event of: Unit failure Inter-unit stacking link failure Unit insertion Unit removal When the Master unit boots, or when inserting or removing a stack member, the Master unit initiates a stacking discovering process. 44 Dell PowerConnect 55xx Systems User Guide - Dell PowerConnect 5524P | User Guide - Page 45
this process until all units are connected. 3 (Optional) Connect the left-hand HDMI port of the unit at the bottom of the stack to the right-hand HDMI port of the unit at the top of the stack. This step provides increased bandwidth and redundancy. Dell PowerConnect 55xx Systems User Guide 45 - Dell PowerConnect 5524P | User Guide - Page 46

To assign IDs to the units in the stack, do the following for each unit in the stack: 1 Connect the unit to the terminal. 48 Dell PowerConnect 55xx Systems User Guide - Dell PowerConnect 5524P | User Guide - Page 49
Master Backup, according to the following decision process: • A master is selected from the set of the two Master-enabled units. Priority is given to the lowest unit ID, but also takes into account the amount of time the unit is UP (Up Time) as follows: Dell PowerConnect 55xx Systems User Guide 49 - Dell PowerConnect 5524P | User Guide - Page 50
Master unit is removed from the stack and the user wishes to configure one of the slave units (numbered 3-8) to be a Master backup, the user must reset the unit's ID. This can be done as follows: • If there is a Master-enabled unit in the stack: Do -switch n renumber 2 (through CLI or GUI). This - Dell PowerConnect 5524P | User Guide - Page 51
events occur: • The Stack Master fails or is removed from the stack. • Links from the Stack Master to the stacking members fails. • User performs soft switchover via the Web interface or the CLI. Switching between the Stack Master and the Master Backup results in limited service loss. Dynamic tables - Dell PowerConnect 5524P | User Guide - Page 52
