    Switch from the console program. The DES-3226S contains a CPU, memory for data storage, flash memory for configuration data, operational programs, and SNMP agent firmware. These components allow the Switch to be actively managed and monitored from either the console port or the network itself (out-of-band, or in-band).

  • Page 27: Stacking Vs. Standalone Operation (Release 4.01)

    Auto: This is the default stacking mode setting for the DES-3226S. In auto stacking mode the Switch is eligible for stacking or it can operate as a standalone device. If a DES-3226S Switch stack is connected and all units are configured to operate in auto stacking mode, the master-slave relationships is determined automatically.

  • Page 28: Managing Switch Stacks

    Changes to Switch Stack Structure If Switches are added to or taken out of a stacked group of DES-3226S Switches it is necessary to change the composition of a Switch stack and rearrange the stacking connections. If a stacking link fails or if a member of a stacked group fails, the composition of the stack will necessarily change also.

    DES-3226S Layer 2 Fast Ethernet Switch User’s Guide Switch IP Address 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. You can change the default Switch IP Address to meet the specification of your networking address scheme.

  • Page 33: Snmp Network Management

    SNMP Versions 1, 2 and 3 The DES-3226S supports SNMP version 3 as well as versions 1 and 2. The chief difference between Version 3 (SNMP v.3) and Versions 1 and 2 (SNMP v.1 and SNMP v.2) is that it provides a substantially higher level of security than the previous versions.

  • Page 34: Forwarding And Filtering

    Filtering and Access Profile Masking The DES-3226S Switch can use a form of manually configured packet filtering to segment the network and control communication between segments. It can also filter packets off the network for intrusion control. Filtering is done by setting up an Access Profile Mask.

  • Page 35: 802.1W Rapid Spanning Tree

    DES-3226S Layer 2 Fast Ethernet Switch User’s Guide Additional criteria are applied to the forwarding decision. Depending on what header information is being examined, forwarding is permitted or denied based on the packet’s source or destination, its protocol classification, DiffServ code, 802.1p level or VLAN.

  • Page 36: Link Aggregation

    The DES-3226S supports link aggregation groups, which may include from 2 to 8 Switch ports each, except for a Gigabit link aggregation group which consists of the 2 (optional) Gigabit Ethernet ports of the front panel. These ports are the two 1000BASE-SX, -LX –TX or GBIC ports contained in a front-panel mounted module.

  • Page 37: Vlans

    Egress port - A port on a Switch where packets are flowing out of the Switch, either to another Switch or to an end station, and tagging decisions must be made. IEEE 802.1Q (tagged) VLANs are implemented on the DES-3226S Switch. 802.1Q VLANs require tagging, which enables the VLANs to span an entire network (assuming all Switches on the network are IEEE 802.1Q-compliant).

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.

    Asymmetric VLANs The DES-3226S supports Asymmetric VLANs implementation for more efficient use of shared resources such as server or gateway devices. An asymmetric VLAN can be set up to allow a server (or several servers) to communicate with several clients through a single physical link on the Switch.
