8.6 IP Setup
Use the IP Setup screen to configure the default gateway device, the default domain name server and
add IP domains.
8.6.1 IP Interfaces
The Switch needs an IP address for it to be managed over the network. The factory default IP address is
192.168.1.1. The subnet mask specifies the network number portion of an IP address. The factory default
subnet mask is 255.255.255.0.
You can configure up to 32 IP domains which are used to access and manage the Switch from the ports
belonging to the pre-defined VLANs.
Note: You must configure a VLAN first. Each VLAN can have multiple management IP
addresses, and you can log into the Switch through different management IP
addresses simultaneously.
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 eight 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).
To map a priority level to a physical queue, select a physical queue from the drop-down menu on the right.
Priority 7 Typically used for network control traffic such as router configuration messages.
Priority 6 Typically used for voice traffic that is especially sensitive to jitter (jitter is the variations in delay).
Priority 5 Typically used for video that consumes high bandwidth and is sensitive to jitter.
Priority 4 Typically used for controlled load, latency-sensitive traffic such as SNA (Systems Network
Architecture) transactions.
Priority 3 Typically used for “excellent effort” or better than best effort and would include important
business traffic that can tolerate some delay.
Priority 2 This is for “spare bandwidth”.
Priority 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.
Priority 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 begin configuring this screen afresh.
