GARLAND TECHNOLOGY FAB10GXXXX (01) PDF Document

To access the command line interface of the GARLAND TECHNOLOGY FAB10GXXXX via a serial terminal emulator, use the following settings:

The GARLAND TECHNOLOGY FAB10GXXXX has a “root” account which grants full access and permissions. The default credentials are:

Username: root

Password: gtroot1

To create additional user accounts via the command line interface on the GARLAND TECHNOLOGY FAB10GXXXX, use the following commands:

1. Enter global configuration mode: cmd# configure terminal

2. Create the new user: cmd(config)# username <user> password <password>

The GARLAND TECHNOLOGY FAB10GXXXX allows different modes or levels when configuring the device via the command line interface:

device# | This is the initial mode after logging in as root. It allows users to access the configuration of the device.

device(config)# | Executing the `configure terminal` command enters this global configuration mode.

device(config-if)# | From the global configuration, executing `interface <interface type><interface ID>` allows for interface-specific configurations.

device(config)# configuration map (1-4000) | From the global configuration, this mode allows users to create port configuration maps. You can query command options using `help` or `?`.

To change the management port’s default IP address (10.10.10.200) on the GARLAND TECHNOLOGY FAB10GXXXX, use the following commands:

1. cmd# configure terminal

2. cmd(config)# interface cpu0

3. cmd(config-if)# ip address <ip_addr> <subnet_mask>

To set the gateway IP address on the GARLAND TECHNOLOGY FAB10GXXXX, use the following commands:

1. cmd# configure terminal

2. cmdt(config)# ip route 0.0.0.0 0.0.0.0 <gateway_ip>

If you encounter a “No OOB port exists” error on the GARLAND TECHNOLOGY FAB10GXXXX, execute the following commands in order:

1. cmd# erase startup-config

2. cmd# erase nvram

3. cmd# reload

After setting the management port’s IP address, you can access the graphical user interface of the GARLAND TECHNOLOGY FAB10GXXXX.

1. Open a web browser and navigate to Http://<ip_addr> (replace <ip_addr> with the device’s management IP).

2. Use the following credentials to log in:

Username: root

Password: gtroot1

Follow these steps to create, configure, and save a new configuration map using the web interface:

1. Navigate to Load Balancer > Configuration Maps in the main menu.

2. Click the New button to start creating a new map.

3. At the top of the screen, select the ports, groups, or filter templates you wish to use.

4. Drag and drop ports from the selection area into the Input Ports and Output Ports/Groups sections of the configuration map builder.

5. Drag and drop filter templates from the selection area into the Filters/Rules section between the input and output ports.

6. Click on the default map name (e.g., “New Configuration Map”) to name the configuration map and provide a helpful description, then click “done”.

7. In the Filters/Rules section, click edit on the filter to open the “Filter Properties” window.

8. In the Filter Criteria tab, select the filter mode (e.g., Pass by criteria, Deny by criteria) and the criteria type (e.g., Layer 2, Layer 3/4 (IPv4), IPv6). Fill in the specific criteria such as MAC addresses, IP addresses, or VLAN ID.

9. In the Advanced Action tab, select any additional actions to perform on the filtered traffic, such as “Strip vlan” or “Tag vlan”. Click Save to close the filter properties window.

10. Click the main Save button on the configuration map page to save the new map.

11. To make the new configuration persistent across reboots, navigate to System > Save Configuration, ensure “Flash Save” is selected, and click Apply.

To configure the Load Balancing Policy on the GARLAND TECHNOLOGY FAB10GXXXX via the web interface, navigate to Load Balancer > Load Balancer Policy. On this screen, you can configure the following:

Hash Index Type:

Select the hashing algorithm to be used for distributing traffic. Options include:

– XOR Based

– CRC Based

– CRC-16 Based

Selection Policy:

Choose the packet header fields to include in the hashing calculation. Multiple options can be selected. Options include:

– MAC Source

– MAC Destination

– IP Source

– IP Destination

– MPLS Label 0, 1, or 2

– Ipv6 Destination

– Ipv6 Source

– Source L4 Port

– Destination L4 Port

After making your selections, click Apply to save the policy.

To save the current configuration to the device’s flash memory, use the web interface:

1. Navigate to System > Save Configuration in the main menu.

2. On the “Save configuration” page, ensure the Save option is set to Flash Save.

3. You can optionally change the File Name from the default “iss.conf”.

4. Click the Apply button to save the configuration.

This action will save the current configuration, ensuring that your settings are retained after the device is rebooted.

A typical deployment scenario for the GARLAND TECHNOLOGY FAB10GXXXX involves three main stages:

1. Access: Traffic is collected from the network using various methods like GT Fiber Taps (1G/10G), GT Copper Taps (10/100/1G), or from SPAN/monitor port feeds.

2. Processing: The collected traffic is sent to the GT FAB 48 Port Device (FAB10GXXXX). The device performs functions such as aggregation, regeneration, filtering, balancing, and tag stripping on the traffic.

3. Monitoring: The processed traffic is then forwarded from the FAB to various monitoring tools for analysis, IDS, compliance checks, trending, QA, and packet capture.

In a flow-based load balancing scenario, the GARLAND TECHNOLOGY FAB10GXXXX is used to distribute traffic from multiple tapped links to multiple analysis tools while maintaining session integrity. The process is as follows:

1. Multiple network links are tapped using full-duplex taps.

2. The tap outputs, representing both request and reply traffic, are connected to the Line Rate 1G/10G Inputs of the FAB (e.g., ports 1, 3, 5, 7).

3. The FAB processes this traffic, applying filtering and aggregation rules based on user-defined session flows.

4. The FAB then performs flow-based load balancing, ensuring that related traffic flows (e.g., both sides of a conversation) are sent to the same output port.

5. The balanced traffic is sent from the 1G/10G Outputs (e.g., ports 2, 4, 6, 8) to multiple analysis servers, ensuring 100% monitoring fidelity without overloading any single tool.

The GARLAND TECHNOLOGY FAB10GXXXX can be deployed to remove VLAN or MPLS tags from network traffic before forwarding it to monitoring tools that may not be able to process tagged frames. The scenario works as follows:

1. Full-duplex taps are placed on network links carrying tagged traffic (e.g., frames with Tag 1 and Tag 2).

2. The tap outputs are sent to the 1G/10G input ports of the Filtering Aggregating Balancer (FAB).

3. The FAB is configured with rules to identify and strip the VLAN/MPLS tags from the incoming packets.

4. When stripping the tags, the FAB also recalculates and applies a new CRC (Cyclic Redundancy Check) to the modified packet to ensure packet integrity.

5. The untagged 1G/10G traffic is then sent out of the FAB’s output ports to the connected monitor tools.
