  • Page 103: Using A Port Mirror For Analysis

    Using a Port Mirror for Analysis Using a Port Mirror for Analysis You can mirror traffic from any source port to a target port for real-time analysis. You can then attach a network sniffer or RMON probe to the target port and study the traffic crossing the source port in a completely unobtrusive manner.
  • Page 104 Web Interface Use the Port Trunking Configuration screen to set up port trunks as shown below. Remember that you must “Enable” a new configuration before it will take effect. Parameter Description Trunk Number A unique identifier for this trunk. You can configure up to four trunks per switch.

    Port Statistics Port Statistics Use the Port Statistics menu to display Etherlike or RMON statistics for any port on the switch. Select the required port. The statistics displayed are indicated in the following figure and table. Etherlike Statistics Etherlike Statistics display key statistics from the Ethernet-like MIB for each port. Error statistics on the traffic passing through each port are displayed.

  • Page 106: Rmon Statistics

    Web Interface RMON Statistics RMON Statistics display key statistics for each port from RMON group 1. (RMON groups 2, 3 and 9 can only be accessed using SNMP management software.) The following screen displays overall statistics on traffic passing through each port. RMON statistics provide access to a broad range of statistics, including a total count of different frame types passing through each port.
  • Page 107 Port Statistics Parameter Description 64 Byte Frames The total number of frames (including bad packets) received and transmitted that were 64 octets in length (excluding framing bits but including FCS octets). 65-127 Byte Frames The total number of frames (including bad packets) received and transmitted that were between 65 and 127 octets in length inclusive (excluding framing bits but including FCS octets).

  • Page 109: Chapter 4: Advanced Topics

    Chapter 4: Advanced Topics The Alcatel OmniStack ® 8008 supports Layer 2 switching and other advanced features, which are described in this chapter. Layer 2 Switching When a frame enters a port, its destination MAC address is checked in the address database to see which port leads to this destination.

  • Page 110: Virtual Lans

    Advanced Topics Once a stable network topology has been established, all bridges listen for Hello BPDUs (Bridge Protocol Data Units) transmitted from the Root Bridge. If a bridge does not get a Hello BPDU after a predefined interval (Maximum Age), the bridge assumes that the link to the Root Bridge is down.

  • Page 111: Assigning Ports To Vlans

    Virtual LANs This switch supports the following VLAN features: • Up to 256 VLANs can be configured based on the IEEE 802.1Q standard • Distributed VLAN learning across multiple switches using explicit or implicit tagging and GVRP protocol • Port overlapping, allowing a port to participate in multiple VLANs •...

  • Page 112: Forwarding Traffic With Unknown Vlan Tags

    Advanced Topics This allows GVRP-compliant devices to be automatically configured for VLAN groups based solely on endstation requests. Forwarding Traffic with Unknown VLAN Tags This switch only supports 256 VLANs with VLAN IDs ranging from 1 to 2048, but the IEEE 802.1Q VLAN standard allows for VLAN IDs from 1 to 4094.

  • Page 113: Multicast Filtering

    Multicast Filtering Multicast Filtering Multicasting sends data to a group of nodes instead of a single destination. The simplest way to implement multicasting is to broadcast data to all nodes on the network. However, such an approach wastes a lot of bandwidth if the target group is small compared to overall the broadcast domain.

  • Page 114: Class-Of-Service (Cos) Support

    Advanced Topics Class-of-Service (CoS) Support The OmniStack ® 8008 provides two transmit queues on each port, with a Weighted Fair Queuing scheme. This function can be used to provide independent priorities for various types of data such as real-time video or voice, and best-effort data. Priority assignment to a packet in the OmniStack ®...

  • Page 115: Remote Monitoring

    Remote Monitoring Remote Monitoring Remote Monitoring (RMON) provides a cost-effective way to monitor large networks by placing embedded or external probes on distributed network equipment (hubs, switches or routers). Network management software can access the probes embedded in recent Alcatel network products to perform traffic analysis, troubleshoot network problems, evaluate historical trends, or implement proactive management policies.
