Page 30: First Time Connecting To The Switch
DES-3526 / DES-3526DC Fast Ethernet Layer 2 Switch First Time Connecting to The Switch The Switch supports user-based security that can allow you to prevent unauthorized users from accessing the Switch or changing its settings. This section tells how to log onto the Switch.
Page 31: Password Protection
DES-3526 / DES-3526DC Fast Ethernet Layer 2 Switch Password Protection The DES-3526 does not have a default user name and password. One of the first tasks when settings up the Switch is to create user accounts. If you log in using a predefined administrator-level user name, you have privileged access to the Switch's management software.
Page 32: Snmp Settings
MIB specifications and the protocol used to access this information over the network. The DES-3526 supports SNMP versions 1, 2c, and 3. You can specify which version of SNMP you want to use to monitor and control the Switch. The three versions of SNMP vary in the level of security provided between the management station and the network device.
Page 33: Ip Address Assignment
DES-3526 / DES-3526DC Fast Ethernet Layer 2 Switch MIBs The Switch in the Management Information Base (MIB) stores management and counter information. The Switch uses the standard MIB-II Management Information Base module. Consequently, values for MIB objects can be retrieved from any SNMP-based network management software. In addition to the standard MIB-II, the Switch also supports its own proprietary enterprise MIB as an extended Management Information Base.

Page 47: Link Aggregation
Port trunk groups are used to combine a number of ports together to make a single high-bandwidth data pipeline. The DES-3526 supports up to six port trunk groups with 2 to 8 ports in each group. A potential bit rate of 8000 Mbps can be achieved.
Page 48 DES-3526 / DES-3526DC Fast Ethernet Layer 2 Switch Figure 6- 7. Example of Port Trunk Group The Switch treats all ports in a trunk group as a single port. Data transmitted to a specific host (destination address) will always be transmitted over the same port in a trunk group. This allows packets in a data stream to arrive in the same order they were sent.

DES-3526 / DES-3526DC Fast Ethernet Layer 2 Switch The DES-3526 supports IEEE 802.1Q VLANs and Port-Based 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.

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.
