    DGS-3224TGR Gigabit Ethernet Switch User’s Guide IP Addresses and SNMP Community Names Each switch must be assigned its own IP Address, which is used for communication with an SNMP network manager or other TCP/IP application (for example BOOTP, TFTP). The switch’s default IP address is 10.90.90.90.

  • Page 25: Mibs

    DGS-3224TGR Gigabit Ethernet Switch User’s Guide You can also specify which network managers may receive traps from the switch by entering a list of the IP addresses of authorized network managers. Up to four trap recipient IP addresses, and four corresponding SNMP community strings can be entered.

  • Page 26: Snmp

    • Modifying the configuration of network devices. The DGS-3224TGR has a software program called an ‘agent’ that processes SNMP requests, but the user program that makes the requests and collects the responses runs on a management station (a designated computer on the network). The SNMP agent and the user program both use the UDP/IP protocol to exchange packets.

    Spanning Tree 802.1w Rapid Spanning Tree The DGS-3224TGR implements two versions of the Spanning Tree Protocol, the Rapid Spanning Tree Protocol (RSTP) as defined by the IEE 802.1w specification and a version compatible with the IEEE 802.1d STP. RSTP can operate with legacy equipment implementing IEEE 802.1d, however the advantages of using RSTP will be lost.

    VLAN membership, packets cannot cross VLANs without a network device performing a routing function between the VLANs. 2. The DGS-3224TGR supports only IEEE 802.1Q VLANs. The port untagging function can be used to remove the 802.1Q tag from packet headers to maintain compatibility with devices that are tag-unaware.

  • Page 30: 802.1Q Vlan Packet Forwarding

    DGS-3224TGR Gigabit Ethernet Switch User’s Guide VLANs can also provide a level of security to your network. IEEE 802.1Q VLANs will only deliver packets between stations that are members of the VLAN. Any port can be configured as either tagging or untagging. The untagging feature of IEEE 802.1Q VLANs allows VLANs to work with legacy switches that don’t recognize VLAN tags in packet headers.

    DGS-3224TGR Gigabit Ethernet Switch User’s Guide Figure 5-1. IEEE 802.1Q Packet Forwarding 802.1Q VLAN Tags The figure below shows the 802.1Q VLAN tag. There are four additional octets inserted after the source MAC address. Their presence is indicated by a value of 0x8100 in the EtherType field. When a packet’s EtherType field is equal to 0x8100, the packet carries the IEEE 802.1Q/802.1p tag.

IEEE 802.1Q Tag The EtherType and VLAN ID are inserted after the MAC source address, but before the original EtherType/Length or Logical Link Control.

    DGS-3224TGR Gigabit Ethernet Switch User’s Guide If the packet is not tagged with VLAN information, the ingress port will tag the packet with its own PVID as a VID. The switch then determines if the destination port is a member of the same VLAN (has the same VID) as the ingress port.
