  • Page 9: In-Band Connections

    Management Guide In-Band Connections Prior to accessing the switch’s embedded agent via a network connection, you must first configure it with a valid IP address, subnet mask, and default gateway using an out-of-band connection or the BOOTP protocol. Note: The switch will automatically issue BOOTP requests if the IP address is set to “0.0.0.0”.

    CheetaSwitch Workgroup-3616 Filtering After learning the address, the switch checks: Whether the source port or destination port is in the forwarding state. The source MAC address or destination MAC address to be filtered. That the source port ID is the same as the destination port ID. If any of these conditions are met, the switch drops the received frame.

  • Page 59: Spanning Tree Protocol

    Management Guide Spanning Tree Protocol The Spanning Tree Protocol (that is, the STP configuration algorithm as outlined in IEEE 802.1D) can be used to detect and disable network loops, and to provide link backup. This allows the switch to interact with other bridging devices (including STP-compliant switches, bridges or routers) in your network to ensure that only one route exists between any two stations on the network.

  • Page 60: Basic Functions Of Layer-3 Switching

    • Verifying and recalculating the Layer-3 checksum Routing Protocols The ES3616 supports both static routing and dynamic routing. Static routing requires routing information to be stored in the switch, either manually or when a connection is set up, by an application outside the switch.

  • Page 61: Packet-By-Packet Routing Switch

    (see RFC 1388). Packet-by-Packet Routing Switch The ES3616 forwards incoming Layer-3 packets and uses the CPU for routing path management. If the switch receives a packet with a destination MAC that does not match the switch's MAC address, the switch reverts to Layer-2 switching.

  • Page 62: Icmp Router Discovery

    CheetaSwitch Workgroup-3616 The switch uses two copies of the routing table information to determine the necessary forwarding information: a master copy of the whole routing table that is stored and maintained by the switch and a subset of the routing table that is saved in its local Layer-3 switching database.

  • Page 63: Assigning Ports To Vlans

    Management Guide An IEEE 802.1Q VLAN is a group of ports that can be located anywhere in the network, but communicate as though they belong to the same physical segment. VLANs help to simplify network management by allowing you to move devices to a new VLAN without having to change any physical connections.

This allows GVRP-compliant devices to be automatically configured for VLAN groups based solely on endstation requests. Forwarding Traffic with Unknown VLAN Tags This switch only supports 64 VLANs, but up to 4094 VLANs are supported by the IEEE 802.1Q VLAN protocol.

  • Page 65: Port Overlapping

    Layer-2 switching is used for intra-VLAN traffic. Class-of-Service (CoS) Support The ES3616 provides four transmit queues on each port, with a weighted round- robin scheme. These functions can be used to provide independent priorities for various types of data including real-time video, real-time voice, and best-effort data.

  • Page 66: Igmp Snooping And Ip Multicast Filtering

    BOOTP/DHCP Relay, described in RFC 1542, enables a host to use a BOOTP or DHCP server to obtain basic TCP/IP configuration information, even if the servers do not reside on the local subnet. When an ES3616 with BOOTP/DHCP Relay Agent receives a DHCP Request packet destined for a BOOTP/DHCP server, it inserts its own IP address into the DHCP Request packet so the server knows the subnet where the client is located.
