configurable except by setting priority below) the switch’s MAC address. The Bridge Identifier consists of two parts: a 16-bit priority and a 48-bit Ethernet MAC address 32768 + MAC Priority A relative priorit y for each switch – lower numbers give a higher priorit y and a greater chance of a given s witch being elected as the root bridge 32768[...]

parameters in the Switch are as follows: Priority – A Priority for the swit ch can be set from 0 to 65535. 0 is equal to the highest Prio rity .

between switch B and C is deliberate ly chosen as a 100 Mbps Fast Ethernet link (default port cost = 19). Gigabit ports could be used, but the port cost should be increased from t he default to ensure that the link between switch B and s witch C is the blocked link. 4.6.2 S p anning T ree Configuration The S panning T ree Protocol (STP) operates on[...]

the default setting is 128.The lo wer number has the highest priority . Path Cost: S pecifies the path cost of the port. The switch uses this p arameter to help determine which port will become a for warding port. Lower numbers will be used as forwarding ports first. The range is from 0 to 65535. The default values based on I EEE802.1D are: 10Mb/s [...]

It allows a maximum of eight p orts to be aggregated at the same time and up to 12 groups. If the group is defined as a LACP static link aggregationing group, then any extra ports selected are placed in a standby mode for redundancy if one of the other ports fails . If the group is defined as a local static link aggregationing group, then the numb [...]

transmissions warrant special consideratio n. The Switch allows you to further tailor how priority tagged data packets are handled on your network. Using queues to manage pri ority tagged data allows you to specify its relative priority to suit the needs of your network. There may be circumstances where it would be advantageous to group t wo or mor[...]
