8.6 IP Setup
Use the IP Setup screen to configure the Switch IP address, default gateway
device, the default domain name server and the management VLAN ID. The
default gateway specifies the IP address of the default gateway (next hop) for
outgoing traffic.
Leave All
Timer
Leave All Timer sets the duration of the Leave All Period timer for GVRP in
milliseconds. Each port has a single Leave All Period timer. Leave All
Timer must be larger than Leave Timer.
Priority Queue Assignment
IEEE 802.1p defines up to eight separate traffic types by inserting a tag into a MAC-layer
frame that contains bits to define class of service. Frames without an explicit priority tag
are given the default priority of the ingress port. Use the next fields to configure the
priority level-to-physical queue mapping.
The Switch has eight physical queues that you can map to the 8 priority levels. On the
Switch, traffic assigned to higher index queues gets through faster while traffic in lower
index queues is dropped if the network is congested.
Priority Level (The following descriptions are based on the traffic types defined in the IEEE
802.1d standard (which incorporates the 802.1p).
Level 7
Typically used for network control traffic such as router configuration
messages.
Level 6
Typically used for voice traffic that is especially sensitive to jitter (jitter is
the variations in delay).
Level 5
Typically used for video that consumes high bandwidth and is sensitive to
jitter.
Level 4
Typically used for controlled load, latency-sensitive traffic such as SNA
(Systems Network Architecture) transactions.
Level 3
Typically used for “excellent effort” or better than best effort and would
include important business traffic that can tolerate some delay.
Level 2
This is for “spare bandwidth”.
Level 1
This is typically used for non-critical “background” traffic such as bulk
transfers that are allowed but that should not affect other applications
and users.
Level 0
Typically used for best-effort traffic.
Apply
Click Apply to save your changes to the Switch’s run-time memory. The
Switch loses these changes if it is turned off or loses power, so use the
Save link on the top navigation panel to save your changes to the non-
volatile memory when you are done configuring.
Cancel
Click Cancel to reset the fields.
