Page 417 highlights

DWS-3160 Series Gigabit Ethernet Unified Switch Web UI Reference Guide addresses, specified in the Known Client database and not explicitly granted access, are denied access. If the MAC address is not in the database then the access to the client is granted. RF Scan Status Timeout Enter a time in hour to determine how long to keep an entry in the RF Scan Status (hours) list. Detected Clients Status Enter a time in hour to determine how long to keep an entry in the Detected Client Timeout (hours) Status list. AP Provisioning Database Age Time (hours) Enter a time in hour to determine how long to keep an entry in the AP provisioning database. Tunnel IP MTU Size Select the maximum size of an IP packet handled by the network. The MTU is enforced only on tunneled VAPs. When IP packets are tunneled between the APs and the Unified Switch, the packet size is increased by 20 bytes during transit. This means that clients, configured for 1500 byte, its IP MTU size may exceed the maximum MTU size of existing network infrastructure which is set up to switch and route 1518 (1522-tagged) byte frames. If the tunnel IP MTU size is increased, the physical MTU of the ports on which the traffic flows must also be increased. NOTE: If any of the following conditions are true, there is no need to increase the tunnel IP MTU size: • The wireless network does not use L3 tunneling. • The tunneling mode is used only for voice traffic, which typically has small packets. • The tunneling mode is used only for TCP based protocols, such as HTTP. This is because the AP automatically reduces the maximum segment size for all TCP connections to fit within the tunnel. Cluster Priority Specify the priority of this switch for the Cluster Controller election. The switch with highest priority in a cluster becomes the Cluster Controller. If the priorities are the same among all switches, the switch with lowest IP address becomes the Cluster Controller. A priority of 0 means that the switch cannot become the Cluster Controller. The highest possible priority is 255. AP Client QoS Use the drop-down menu to enable or disable the client QoS feature.

addresses, specified in the Known Client database and not explicitly granted
access, are denied access. If the MAC address is not in the database then the
access to the client is granted.

Tunnel IP MTU Size
Select the maximum size of an IP packet handled by the network. The MTU is
enforced only on tunneled VAPs. When IP packets are tunneled between the APs
and the Unified Switch, the packet size is increased by 20 bytes during transit. This
means that clients, configured for 1500 byte, its IP MTU size may exceed the
maximum MTU size of existing network infrastructure which is set up to switch and
route 1518 (1522-tagged) byte frames. If the tunnel IP MTU size is increased, the
physical MTU of the ports on which the traffic flows must also be increased.
NOTE:
If any of the following conditions are true, there is no need to increase the
tunnel IP MTU size:
The wireless network does not use L3 tunneling.
The tunneling mode is used only for voice traffic, which typically has
small packets.
The tunneling mode is used only for TCP based protocols, such as
HTTP. This is because the AP automatically reduces the maximum
segment size for all TCP connections to fit within the tunnel.
Cluster Priority
Specify the priority of this switch for the Cluster Controller election. The switch with
highest priority in a cluster becomes the Cluster Controller. If the priorities are the
same among all switches, the switch with lowest IP address becomes the Cluster
Controller. A priority of 0 means that the switch cannot become the Cluster
Controller. The highest possible priority is 255.
