Figure 5-1: Example of a port-based VLAN Even though they are physically connected to the same Switch, for the members of the different VLANs to communicate, the trafÞc must go through the IP routing functionality provided in the Summit.
Page 76 In a port-based VLAN, to create multiple VLANs that span two Switches, a port on Switch 1 must be cabled to a port on Switch 2 for each VLAN you want to create. At least one port on each switch must be a member of one of the VLANs, as well.
Page 77: Tagged Vlans
VLANs spanning two Switches. On Switch 1, ports 1-4 are part of VLAN Accounting; ports 5 - 8 are part of VLAN Engineering. On Switch 2, ports 1-4 are part of VLAN Accounting; ports 5 - 8 are part of VLAN Engineering. VLAN Accounting spans Switch 1 and Switch 2 by way of a connection between Switch 1 port 2 and Switch 2 port 4.
Page 78: Uses Of Tagged Vlans
802.1Q tag deÞned, you decide whether each port will use tagging for that VLAN. The default mode of the Switch is to have all ports assigned to the VLAN named Òdefault,Ó without an 802.1Q VLAN tag (VLAN ID) assigned.

Page 81: Protocol Filters
The IP trafÞc has been divided into two IP subnets, 192.207.35.0 and 192.207.36.0. The subnets are internally routed by the Summit. The subnets are assigned different VLAN names, Finance and Personnel, respectively. The remainder of the trafÞc belongs to the VLAN named MyCompany.
Page 82: Defining Protocol Filters
VLAN name that does not begin with an alphabetical character, or that contains a space, comma, or other special character. VLAN names are locally signiÞcant. That is, VLAN names used on one Switch are only meaningful to that Switch. If another Switch is connected to it, the VLAN names have no signiÞcance to the other Switch.
Page 83 The Summit ships with one default VLAN that has the following properties: ¥ The VLAN name is default. ¥ It contains all the ports on a new or initialized Switch. ¥ The default VLAN is untagged on all ports. It has an internal VLAN ID of 1.

Page 103: Quality Of Service (Qos)
The main beneÞt of QoS is that it allows you to have control over the types of trafÞc that receive priority service from the Switch. For example, if video trafÞc requires a higher priority than data trafÞc, using QoS you can assign a different QoS proÞle to those VLANs that are transmitting video trafÞc.
Page 104 ¥ Priority Ñ The level of priority in which this queue will be serviced by the Switch. Choices include: Ñ Low Ñ Normal Ñ Medium Ñ High A QoS proÞle does not alter the behavior of the Switch until it is assigned to a trafÞc classiÞcation. UMMIT WITCH NSTALLATION AND UIDE...
Page 105 REDEFINED The following predeÞned QoS proÞles are provided, depending upon the QoS conÞguration of the Switch: ¥ Implicit QoS Mode Ñ A single QoS mode, called besteffort, is provided. It allows for 0% minimum and 100% maximum bandwidth along with a low-priority setting. Up to 15 other QoS proÞles may be deÞned.

Page 111: Dynamic Routes
IP U VERVIEW OF NICAST OUTING YNAMIC OUTES Dynamic routes are typically learned by way of RIP. Routers that use RIP exchange information in their routing tables in the form of RIP advertisements. Using dynamic routes, the routing table contains only networks that are reachable. Dynamic routes are aged out of the table when a RIP update for the network is not received for a period of time.
Page 112: Configuring Ip Unicast Routing
When you create a VLAN, RIP is enabled by default. You must, however, enable RIP on the Switch in order to route trafÞc. To disable RIP on a particular VLAN, use the following command: — config rip delete {vlan <name>}...

Page 135: About Rmon
RMON BOUT RMON is the common abbreviation for the Remote Monitoring Management Information Base (MIB) system deÞned by the Internet Engineering Task Force (IETF) documents RFC 1271 and RFC 1757, which allows you to monitor LANs remotely. A typical RMON setup consists of the following two components: ¥...
Page 136: Rmon And The Switch
WITCH RMON requires one probe per LAN segment, and standalone RMON probes have traditionally been expensive. Therefore, ExtremeÕs approach has been to build an inexpensive RMON probe into the agent of each Switch. This allows RMON to be widely deployed around the network without costing more than traditional network management.
Page 137 For example, statistics can be related to individual ports. Also, because a probe must be able to see all trafÞc, a stand-alone probe must be attached to a nonsecure port. Implementing RMON in the Switch means that all ports can have security features enabled.

Switch correctly when invoking the Telnet facility. Check that Telnet access was not disabled for the Switch. If you attempt to log in and the maximum number of Telnet sessions are being used, you should receive an error message indicating so.
Page 151 A network problem may be preventing you accessing the device over the network. Try accessing the device through the console port. Check that the community strings conÞgured for the Switch and the Network Manager are the same. Check that SNMP access was not disabled for the Switch.
Page 152 ROUBLESHOOTING You forget your password and cannot log in: If you are not an administrator, another user having administrator access level can log in, delete your user name, and create a new user name for you, with a new password. Alternatively, another user having administrator access level can log in and initialize the device.
Page 153 Remember that VLAN names are only locally signiÞcant through the command-line interface. In order for two Switches to communicate across a 802.1Q link, the VLAN ID for the VLAN on one Switch should have a corresponding VLAN ID for the VLAN on the other Switch.
Page 154 ROUBLESHOOTING The Switch keeps aging out endstation entries in the Switch Forwarding Database (FDB): Reduce the number of topology changes by disabling STP on those Switches that do not use redundant paths. Specify that the endstation entries are static or permanent.
