. Port power can be automatically turned on and off for connected devices, and a per-port power priority can be set so that the Switch never exceeds its allocated power budget . When a device is connected to a port, its power requirements are detected by the Switch before power is supplied .
If DHCP/BOOTP is enabled, IP will not function until a reply has been received from the server . Requests will be broadcast periodically by the Switch for an IP address . (DHCP/BOOTP values can include the IP address, subnet mask, and default gateway .)
Management VLAN ID of the configured VLAN (1-4094, no leading zeroes) . By default, all ports on the Switch are members of VLAN 1 . However, the management station can be attached to a port belonging to any VLAN, as long as that VLAN has been assigned an IP address .
Switch periodically sends a request for a time update to a configured time server . You can configure up to two time server IP addresses . The Switch will attempt to poll each server in the sequence . Setup > Time...
. Use the full-duplex mode on ports whenever possible to double the throughput of switch connections . Flow control should also be enabled to control network traffic during periods of congestion and prevent the loss of packets when port buffer thresholds are exceeded .
Cisco EtherChannel standard . For dynamic LAGs, the switches have to comply with LACP . This Switch supports up to four LAGs . For example, a LAG consisting of two 1000 Mbps ports can support an aggregate bandwidth of 4 Gbps when operating at full duplex .

. RADIUS servers provide a centralized authentication method for web access . Up to 5 RADIUS servers can be configured . The Switch attempts authentication using the listed sequence of servers . The process ends when a server either approves or denies access to a user .
RADIUS authentication server to verify user identity and access rights . When a client connects to a switch port, the Switch responds with an EAPOL identity request . The client provides its identity (such as a user name) in an EAPOL response to the Switch, which it forwards to the RADIUS server .
MAC addresses that are authorized to access the network through that port . When port security is enabled on a port, the Switch stops learning new MAC addresses on the specified port when it has reached a configured maximum number .
. When entering addresses for the same group (i .e ., SNMP, web or Telnet), the Switch will not accept overlapping address ranges . When entering addresses for different groups, the Switch will accept overlapping address ranges .
SSH Server-Key Sze (12-8) key size . The server key is a private key that is never shared outside the Switch . The host key is shared with the SSH client, and is fixed at 1024 bits . (Default:8) Security > SSH Host-Key Settings A host public/private key pair is used to provide secure communications between an SSH client and the Switch .
Class of Service (CoS) allows you to specify which data packets have greater precedence when traffic is buffered in the Switch due to congestion . The Switch supports CoS with four priority queues for each port . Data packets in a port’s high-priority queue will be transmitted before...
24-Port 10/100 + 4-Port Ggabt Swtch wth WebVew and Power over Ethernet Configuring the Switch Queue Settings You can set the Switch to service the queues based on a strict rule that requires all traffic in a higher priority queue to be processed before lower priority queues are serviced, or use Weighted Round-Robin (WRR) queuing that specifies a relative weight of each queue .
Differentiated Services Code Point (DSCP) service . When these services are enabled, the priorities are mapped to a Class of Service value by the Switch and the traffic then sent to the corresponding output queue . Because different priority information may be contained in the traffic, the...

The slower the media, the higher the cost . Desgnated Port The port priority and number of the port on the designated bridging device through which the Switch must communicate with the root of the Spanning Tree . Desgnated Brdge The bridge priority and MAC address of the device through which this port must communicate to reach the root of the Spanning Tree .
Defines the priority used for this port in the Spanning Tree Protocol . If the path cost for all ports on a switch are the same, the port with the highest priority (i .e ., lowest value) will be configured as an active link in the Spanning Tree .
. One or more VLANs can be grouped into a Multiple Spanning Tree Instance (MSTI) This Switch supports 33 MSTI’s . MSTP builds a separate Multiple Spanning Tree (MST) for each instance to maintain connectivity among each of the assigned VLAN groups .
• A port on a network segment with no other STA compliant bridging device is always forwarding . If two ports of a switch are connected to the same • segment and there is no other STA device attached to this segment, the port with the smaller ID forwards packets and the other is discarding .
Defines the priority used for this port in the Spanning Tree Protocol . If the path cost for all ports on a switch are the same, the port with the highest priority (i .e ., lowest value) will be configured as an active link in the Spanning Tree .
