10 Mbps of dedicated bandwidth depending on loop length. The BitStorm 2400 IP DSLAM interfaces with a router or switch on the WAN side, and StormPort™ CPE modems on the LAN side. Features available within the BitStorm 2400 are accessible via SNMP software, such as StormTracker™...
1. BitStorm 2400 Overview Features Based on EtherLoop technology, the BitStorm 2400 IP DSLAM has the following features: Compact size (height = 1RU) Shelf-mountable (up to eight units high) and rack-mountable Low price per port Up to 24 ports 10 Mbps EtherLoop —...
1. BitStorm 2400 Overview EtherLoop EtherLoop, like Ethernet, is a “burst-mode” technology – it transmits only when there is information to send. In contrast, conventional copper access technologies maintain constant signal, regardless of whether or not there is information to send.
Traffic Aggregation The integrated Layer 2+ BitStorm 2400 IP DSLAM aggregates the traffic to and from the gigabit Ethernet interfaces. It operates as a multi-port Layer 2+ Ethernet bridge per the IEEE 802.1D/802.1Q specifications. The BitStorm 2400 IP DSLAM and EtherLoop lines support the forwarding of IEEE 802.1Q tagged VLANs and...
802.1p which is a subsection of the 802.1D standard. The 802.1p is carried in a 3-bit field in the IEEE 802.1Q tag. The BitStorm 2400 classifies frames based on the presence and code points (values) of priority information in the IEEE 802.1Q tag.
0 to 3 are directed to the low priority queue. The output frame schedulers on the BitStorm 2400 picks frames from the high priority queue ahead of any frames on the low priority queue. The low priority queue may overflow due to lack of servicing by giving preference to the high priority queue.
Page 17
VLAN Frame Forwarding Ingress and Egress filtering & forwarding rules Tagging and un-tagging frames as required VLAN support is explicitly implemented at both the BitStorm 2400 and the EtherLoop StormPort modems. Each component operates as a VLAN enabled multiport bridge.
1. BitStorm 2400 Overview Secure VLAN Mode The BitStorm 2400 also extends a secure VLAN mode in the web interface for port-to-port security. In this mode, Etherloop ports can only communicate talk with the WAN side of the network. When a VLAN is in secure mode, packets received on member ports are redirected to the uplink port (25) and not switched to other members.
The result of this flooding is that all users would receive the traffic for all of the multicasts that any user of the BitStorm 2400 had requested. This would quickly overwhelm the bandwidth and resources of the system and end stations.
Because only 23 bits of the 28 bits of the IP multicast address are mapped into the MAC multicast address, this leaves 32 IP multicast addresses mapped into a single MAC multicast address. The CO and the BitStorm 2400 both need to inspect the IP header in the multicast frame to determine the actual IP multicast group for forwarding traffic on the right port.
1. BitStorm 2400 Overview IGMP Protocols IGMP v2 is backward compatible with IGMP v1. IGMP Version 2 extended the IGMP Version 1 standard by adding support for an explicit group leave message and a group specific query message. These new messages greatly improve the efficiency of stopping the multicast flows once a subscriber no longer has interest in the group (has shut down or changed the channel).
1. BitStorm 2400 Overview In an effort to reduce the number of broadcast messages being generated in response to the Query or Group-Specific Query message, all hosts in the broadcast domain will see the reports for other hosts in that group. Hosts that see another’s report will simply reset their timer on that group and will not generate a...
1. BitStorm 2400 Overview IGMP V2 Operation IGMP V2 enhances the IGMP V1 standard by adding explicit messages to allow a host to signal that it is leaving a multicast group and a message for a router to query for hosts interested in a specific group. IGMP V2 join operations operate as they did in IGMP V1.
The BitStorm 2400 supports the efficient forwarding, traffic shaping and accounting for multicast flows. The BitStorm 2400 listens for IGMP V1 or IGMP V2 messages. Upon hearing a solicited or unsolicited report message for group, the BitStorm 2400 must build or...
The parameter sets a number of retries (default 3) and interval (100 ms) that would be allowed to attempt to locate remaining hosts on the BitStorm 2400 or VLAN interface before removing the entry from the forwarding table. Tuning this parameter would be one of the tools for minimizing the effects of ‘channel surfing’...
In the privacy filter system, each modem is programmed with a list of MAC addresses that represent valid gateways for backhaul. The BitStorm 2400 units will only forward traffic downstream that has a source MAC address from this list. The CPE modems will only forward traffic upstream that has a destination MAC address from this list.
Terminology and Conventions System Terminology The following terms are used in this manual and the BitStorm 2400 user interfaces. Port A port is one of the physical interfaces of a BitStorm 2400. These are: MGMT (RJ45) CRAFT (DB9) GigE1 (Copper – RJ45): GigE1 takes priority over GigE2.
Page 28
Figure 2-1. BitStorm 2400 IP DSLAMs Interconnected In this figure, eight BitStorm 2400 units are daisy-chained using the GigE1 of the top unit to connect to the network. The GigE2 port of the top unit is then connected to the GigE1 port of the unit below. This sequence is repeated through the subsequent units to complete the daisy-chaining links.

4. Using the Web Interface Spanning Tree The Spanning Tree Protocol is a link management protocol that provides path redundancy and prevents unwanted loops. Several active paths between stations in a network create loops in the network. In an Ethernet network, only one active path can exist between two stations.
Page 61
4. Using the Web Interface STP defines a tree with a root switch and a loop-free path from the root to all switches in the network. STP forces redundant data paths into a standby state. If a network segment in the spanning tree fails and a redundant path exists, the spanning tree algorithm activates the standby path and recalculates the topology.
4. Using the Web Interface Spanning Tree Port Parameters The Ports option allows you to set Spanning Tree Ports parameters. Figure 4-11. Spanning Tree Port Parameters This page allows you to configure the spanning tree port parameters. To change parameters for a specific port, select the port number from the Port pull-down box. The corresponding port information will then be displayed in the editable row of the table.
4. Using the Web Interface VLANs/Multicast Groups Within VLANs/Multicast Groups, you can configure the following: Current VLANs Static VLANs VLAN/GVRP Ports Current Multicast Group Static Multicast Groups GARP/GMRP Ports Current VLAN Configuration The Current VLANs window displays the setup of active VLANs configured in the Static VLANs option.
This field displays the status of the VLAN. Create Time This is a time stamp indicating when the last VLAN was created since the last BitStorm 2400 reboot. Create time of “0” throughout all fields means that the VLAN was created by to reboot. Port Member Status The remaining portion of this row indicates the state of each port in this VLAN.
Page 65
The Internal VLAN ID is used by the EtherLoop Management Agent to communicate with the modems in the BitStorm 2400. There is no need to alter it, but it must not match any other VLAN IDs defined on the unit.
4. Using the Web Interface VLAN/GVRP (GARP VLAN Registration Protocol) Port Configuration The VLAN/GVRP Ports option allows you to modify VLAN/GVRP settings for each port. Figure 4-14. VLAN/GVRP Port Configuration This page lets you modify the VLAN/GVRP configuration for each port. To change the parameters for a specific port, select the port number from the Port pull-down box.
Ingress Filtering This field allows you to Enable or Disable ingress filtering on this port. When this is enabled, the BitStorm 2400 will discard incoming frames for VLANs, which do not include this port in its member set. When disabled, the port will accept all incoming frames.
4. Using the Web Interface Static Multicast Configuration The Static Multicast option allows you to create or delete static Layer 2 multicast groups. Figure 4-16. Static Multicast Configuration This page allows you to create and delete static multicast groups. You create a new group by filling in the following fields and then clicking Apply: Field Description...
4. Using the Web Interface GARP/GMRP Port Configuration GARP (Generic Attribute Registration Protocol) is a protocol that allows a bridge to receive and propagate declarations from network devices for certain attributes. It then creates a path between devices. GARP Multicast Registration Protocol (GMRP) is a Generic Attribute Registration Protocol (GARP) application that provides a constrained multicast flooding facility similar to IGMP snooping and CGMP.
