[. . . ] Sniffer Mode: · · · · · · . Disable - disable port mirroring globally. . RX - mirroring only the ingress traffic to the designated source ports. . TX - mirroring only the egress traffic to the designated source ports. Both - mirroring both incoming and outgoing traffic on the designated source ports. The ports can not be the Sniffer port Switch> Advanced> Jumbo Frame This page allows you to enable or disable the Jumbo Frame support. Jumbo Frames are not an approved standard Ethernet frame size, so you will need to ensure that all of your networking gear can support these non-standard Jumbo Frames to prevent them from being dropped. By clicking 'Help' button on this page, you can see the maximum frame size the switch can carry. Web-Based Management Interface July 2005 4-11 Smart Switch Series Software Manual Switch> Advanced> Spanning Tree Page · Fast Link: When a port running the standard Spanning Tree Protocol (STP) is connected, it will go through the STP negotiation ( listening -> learning -> forwarding or blocking ) before it will be fully available. If a server is trying to access a client through the switch running the STP negotiation, it will not be able to connect to it immediately. Fastlink mode solves this problem by setting the port directly to forwarding mode, thus allowing any server access request to be forwarded. Fastlink mode can cause temporary loops in your network, but the STP will eliminate them. Bridge Priority: Priority setting of this switch in the Spanning Tree. Bridge Max Age: Amount of time before a configuration message is discarded by the system. Bridge Hello Time: Interval between configuration messages sent by the Spanning Tree algorithm. Bridge Forward Delay: Amount of time system spends in 'learning' and 'listening' states. Path Cost: The switch uses this to determine which port is the forwarding port. All other factors equal, the path with the lowest cost to the root bridge will be the active path. Path Priority: STP bases on this to determine the port to use for forwarding. The port with the lowest number has the highest priority. · · · · · · Switch> Advanced> SNMP SNMP page allows you to limit the IP address which can access the MIB of the switch and which the switch will send trap to. The switch will only respond to requests from computers with the IP address in the list. You can also select the traps which the switch will send to the hosts in the following trap events. The setting of a host will not be active until it is set to "Enable" in the Admin field. Trap Events : · · · Device bootup - The switch generates an SNMP trap when it reboots. [. . . ] To further enhance the operation, the cabling standards have been amended. The latest standard is Category 5e, which defines a higher level of link performance than is available with Category 5 cable. If installing new cable, we recommend using Category 5e cable, since it costs about the same as Category 5 cable. If using the existing cable, be sure to have the cable plant tested by a professional who can verify that it meets or exceeds either ANSI/EIA/TIA-568-A:1995 or ISO/ IEC 11801:1995 Category 5 specifications.
