When you configure the password parameter, the factory default setting is deactivated and the new password governs access to the console menus. If you forget your password, contact your Enterasys Networks Support Representative. NOTE: You are automatically logged out from the console menus based on the Lock-out Time setting in the Console Login Configuration Menu. -

Link for the port reads DOWN. 4. If you see a DOWN status for a connected port, plug the cable into another port on the switch or try another cable. -
Page 112: Viewing Switch Statistics
The switch can send SNMP messages called traps to SNMP management stations when an important event occurs with the switch. The switch allows up to five destinations to be configured for these trap messages to be sent. To configure SNMP access for the switch, proceed as follows: 1. -
Page 113: Downloading A Software Upgrade
You can upgrade the operational software in the switch without physically opening the switch or being in the same location. The software storage sector in the flash memory of the switch is reprogrammed, allowing you to easily download software feature enhancements and problem fixes to the switch from a local or remote location. -
Page 114: Downloading Via Tftp
To perform a TFTP download, you must first configure the switch. This consists of programming the switch with an IP address, if this has not already been done, and entering the IP address of the TFTP server and the name of the upgrade file. -

1. Select the Device Control Menu from the Main Menu. 2. Select the Spanning Tree Configuration Menu and then STA Bridge Configuration. 3. Turn the switch Spanning Tree operation on or off by setting the Spanning Tree Protocol field to ENABLED. -
Page 116: Configuring Class Of Service
This switch uses IGMP (Internet Group Management Protocol) to query for any attached hosts who want to receive a specific multicast service. The switch looks up the IP Multicast Group used for this service and adds any port which received a similar request to that group. It then propagates the service request on to any neighboring multicast switch/router to ensure that it will continue to receive the multicast service. -
Page 117: Configuring Port Operation
Default is DISABLED. 4. Set the IGMP Query Count to the number of minutes that must elapse before the switch removes the port from an IGMP group. This timer is started after the number of queries are missed as defined in the IGMP Query Count. -

1. From the Network Monitor Menu, select Static Unicast Address Table Configuration. 2. For the MAC address, specify the VLAN ID, switch port, and the Status (Permanent, Delete On Reset, Lock Port, Unlock Port, Invalid, Delete On Time Out, or Other). -
Page 120: Setting A Default Gateway
The default Gateway parameter defines the IP address of a router or other network device to which IP packets are to be sent if destined for a subnet outside of that which the switch is operating. To set a default gateway, proceed as follows: 1. -

Managed entities supporting SNMP typically contain software, which runs locally on the device and is referred to as an agent. The software in the switch functions as an agent, monitoring and controlling the functionality of the switch. -
Page 124: Mib Objects
RFC 1213 provides management of system-level parameters, including TCP/IP protocol-related statistics, IP addressing, and interface statistics for each switch port. MIB II is the standard MIB defined by RFC 1213. All agent devices operating SNMP are required to support at least part of MIB II. -
Page 125: Rfc 1493 (Bridge Mib)
11.2.5 RFC 1757 (RMON MIB) RFC 1757 is a group defined under MIB II. This MIB provides management for the RMON aspects of the switch. The switch supports four of the nine groups of RMON defined for Ethernet networks on a per port basis. -
Page 126: Ieee 802.1Q (Q Mib)
This MIB provides management for the VLAN aspects of the switch. 11.3 ENTERASYS PROPRIETARY MIB EXTENSIONS Areas of switch functionality not covered by the standard RFC MIBs are specified in the Enterasys private MIB. This MIB definition is specified separately from MIB II. Areas covered in this MIB include various system, switch, and port level information. -
Page 127: Spanning Tree Concepts
A.1.1 Spanning Tree Features The switch meets the requirements of the Spanning Tree Protocol (STP) by BEING ABLE TO performing the following functions: • Create a single spanning tree from any arrangement of switching or bridging elements. -
Page 128: Spanning Tree Protocol In A Network
A and B goes down, the link between A and C becomes active, thereby establishing a path between A and B through switch C. Additionally, if the connection between B and C goes down, the link between A and C becomes active, establishing a path between B and C through switch A. -

SPANNING TREE PROTOCOL PARAMETERS Several configuration parameters control the operation of the Spanning Tree Protocol. describes the parameters and lists the switch default settings for each parameter. NOTE: You can cause serious network performance degradation if you do not fully understand Spanning Tree concepts. -

Table A-1 Spanning Tree Protocol Defaults (Continued) Parameter Description Cost The Spanning Tree Protocol calculates and ensures that an Component of active topology generates minimal cost paths. A value of Each Port 100 is generally used for 10 Mbps Ethernet networks, a value of 19 for 100 Mbps Fast Ethernet, and a value of 4 for 1000 Mbps Gigabit Ethernet. -
Page 131: Handling Duplicate Paths
A.3.5 Handling Duplicate Paths When the active topology of the network is determined, all packets between any two nodes in the network use only one path. Where a duplicate path exists, the non-designated port is put into a blocking state. A.3.6 Remapping Network Topology If there is a change in the network topology due to a failure or the removal or addition of any active... -
Page 133: Virtual Lans (Vlans)
VLANs provide greater network efficiency by reducing broadcast traffic, but also allow you to make network changes without having to update IP addresses or IP subnets. VLANs inherently provide a high level of network security, since traffic must pass through a Layer 3 switch or a router to reach a different VLAN. -
Page 134: Vlan Configuration
VLANs. However, if you want a port on this switch to participate in one or more VLANs, but the device at the other end of the link does not support VLANs, then you must add this port as an untagged port (that is, a port attached to a VLAN-unaware device). -
Page 135: Forwarding Tagged/Untagged Frames
FORWARDING TAGGED/UNTAGGED FRAMES Ports can be assigned to multiple tagged or untagged VLANs. Each port on the switch is therefore capable of passing tagged or untagged frames. To forward a frame from a VLAN-aware device to a VLAN-unaware device, the switch first decides where to forward the frame, and then strips off the VLAN tag. -
Page 137: Class Of Service
• normal As traffic enters the switch, it is assigned to one of the two priority levels according to information located in the 802.1Q header tag of the frame (refer to port number. Frames are then placed into one of two transmit queues on the outbound switch port based on their priority level. -
Page 138: C-1 Class Of Service Example
The tagged header in the frame governs individual frame priority. Figure C-1 shows priority queuing operating within a switch. Frames entering the switch through ports 1 and 4 are tagged as normal traffic and placed in a normal priority queue on the outbound port. -
