    2.11 Using the Stacking Feature The 3524 v.1.1 offers a stacking feature that allows the user to stack up to eight units, all sharing one IP address of the master switch (unit #1). This is an efficient and cost-effective way to add ports as needed. The following lists the characteristics of stacking that the user needs to be aware of: Uses any physical media supported by IC 3524: copper or fiber, Fast Ethernet or Gigabit Ethernet (see the stacking kit {sold separately} shown below);...
  • Page 18 For stacking operation, the stacking feature must first be enabled on each unit (by default, stacking is disabled). Establish a console connection to the first unit. Type k in the Configuration Menu to access the Stacking Management menu. Type t to toggle the switch from “disabled” to “enabled”. Repeat for all remaining units.

    6.3 Community Name and Security SNMP v.1 was not designed to be a secure protocol. There is no true password, although the string known as a community string does serve some of the same purposes. SNMP-aware devices, such as this switch, often ship with well-known community strings. For this reason, it is important that you change the default community strings before putting the switch on a network.

    7.1.3 Port VLAN ID To allow untagged packets to participate in a VLAN, a Port VLAN ID (PVID) must be assigned in the relevant port(s). Each port on the switch has a default PVID of 1 (the default VLAN) and will receive both tagged and untagged frames.

    Forward Delay After a recalculation of the spanning tree, the Forward Delay parameter regulates the delay before each port begins transmitting traffic. If a port begins forwarding traffic too soon (before a new root bridge has been selected), the network can be adversely affected. The default value for Forward Delay is 15 seconds. Note: The above parameters (Hello Time, Maximum Age and Forward Delay) are constrained by the following formula: (Hello Time + 1) <= Maximum Age <= 2 x (Forward Delay –...
  • Page 73 7.3.2 Flow Control With a link operating at a high data rate, a switch may experience occasional limitations in the buffer space used to store Ethernet frames before forwarding them. In this situation, if the sending station continues to send frames, the switch will have no option but to discard the frames. This may quickly lead to unacceptable delays in upper-level protocols.
