EtherXtend 2100 Series SHDSL (formerly referred to as ETHX-SHDSL-LT models)
Firmware Version 1.01.03
July 16, 2008
New Features and Enhancements
New Features
1. Added Standard Bit Error Rate Test (BERT) support for ETHX-21xx devices operating in back-to-back configurations.
2. Changed the total number of Management connections to the device which was limited to two (2) simultaneous connections. The ETHX-21xx devices can now support up to four (4) simultaneous Users connected to Web Management.
Bug Fixes
1. Resolved a QoS issue whereby Ethernet Priority tagged traffic would not be honored on the SHDSL.bis ports if the MTM VLAN rules are set to default.
2. Resolved a DHCP Lease Renewal issue to ensure that the Renewal Timer (T1) and the Rebinding Timer (T2) are set if the ETHX-21xx Management DHCP Client receives an Option 51 (i.e. Lease Time), but does not receive an Option 58 (i.e. Renewal Time) or Option 59 (i.e. Rebinding Time). This will improve compatibility with a number of DHCP Servers which do not always provide Option 58 or Option 59 timer values.
3. Added the Requested IP Address and Host Name to DHCP Request messages for improved compatibility with a number of DHCP Servers.
Known Restrictions and Limitations
SHDSL.bis Data Rates Supported
- The EtherXtend 2100 SHDSL Series EADs supports all data rates from 192 through 5,696 Kbps, in increments of 64 Kbps. Not all 8 Kbps sub-rate increments are supported.
ESIM5700-48 Interop
- Circuits may not train in Adaptive Mode at distances beyond 16kft if connected to an ESIM5700-48 card. Enhancements to the ESIM5700-48 line card have been made in ESIM5700-48 Rev CA and above. Customers experiencing this problem with older revisions of the ESIM5700 line card should use fixed rate mode for problem circuits.
- When interconnecting to an ESIM5700 card in fixed rate mode and set to 3648, 3584, 3456, 3264, or 3200 Kbps, customers may need to manually set the ESIM5700 constellation to TCPAM32 to get the circuits to successfully train at these rates.
- Circuits may not train with an ESIM5700 card when set to a fixed rate mode of 3776 Kbps.
SIM2000-24 Interop
- When interconnecting to a SIM2000-24 card at a fixed rate mode of 784 Kbps, Rx errors can occur at approximately 15 Kft, 19 Kft and 20Kft loop lengths.
ETHX-33x4-SHDSL Access Devices
- When interconnecting to an ETHX-33x4-SHDSL EtherXtend Access Device using Adaptive Rate mode, the two SHDSL circuits (on a 2-port ETHX-2122-SHDSL model) may train at different rates at approximately 4Kft and 11Kft loop lengths. When this occurs, upstream bandwidth (to the ETHX-33x4-SHDSL device) is typically not affected, but downstream throughput can be impaired. If a customer encounters this issue, they should use fixed rate mode to ensure that both circuits train at the same rate.
Compatibility Issues
Firmware version 1.01.01 and greater is not compatible with units that have a BOOT code version lower than 1.00.03. This is mostly limited to pre-GA units shipped prior to June 22, 2007. Any unit with older BOOT code will need to have the PROM updated before upgrading to this or any future releases.
The Zhone/Net-to-Net SNMP standard and proprietary MIBS are extended to support the ETHX-2100 series devices. The current MIBS Definition file is at v1.03.03 and can be downloaded using the following URL:

Additional Notes
Procedure to clear NVRAM
Perform the following procedures to clear NVRAM and restore the device to the factory default settings. This procedure will typically be required if the device has had the default password and/or the default IP address changed and the user wishes to restore these to the factory default settings or if a user wishes to change the operating mode (e.g. change a Provider unit to operate in Subscriber mode).
Step 1) Set the external dip switches in an up-down alternating pattern:
- Switch #1 = UP
- Switch #2 = DOWN
- Switch #3 = UP
- Switch #4 = DOWN
- Switch #5 = UP
- Switch #6 = DOWN
- Switch #7 = UP
- Switch #8 = DOWN
Step 2) Power cycle the device. During the boot cycle, the SHDSL LEDs on the front panel will begin flashing in a repeating cascade pattern. This continues for ten seconds.
Step 3) While the LEDs are flashing, move dipswitch #8 from the "DOWN" to the "UP" position. When this is done, the SHDSL LEDs will stop flashing and remain lit for 5-6 seconds. This indicates that the NVRAM is being cleared. After that, the device will reboot.
Step 4) Reset the dipswitches for the desired configuration / operating modes, and power cycle the device once more. Note that dipswitch #8 is only used for this procedure, and should otherwise be set to the DOWN position after this procedure is completed.
Note that if dipswitch #8 is not changed while the LEDs are flashing in step #3 above, then the boot sequence will continue as normal and the NVRAM will not be cleared. If the dipswitches are not configured in the up-down pattern at boot, then the flashing will not occur and the boot sequence will proceed as normal.
Enhanced Management Functionality
The following enhancements to the ETHX-2100 Management capabilities were added in version 1.01.01 (and higher). The following notes apply to the management functionality
1. For more information on Zhone/Net-to-Net Telnet, Web, CLI and SNMP management capability, please refer to the Command Line Interface User's Guide and SNMP User's Guide for additional information:
http://www.zhone.com/support/manuals/docs/AZ/CLI-A2-GB20-00.pdf
http://www.zhone.com/support/manuals/docs/AZ/SNMP-A2-GB20-00.pdf
2. For more information on Multimedia Traffic Management (MTM) and QoS functionality, please refer to the MTM User's Guide for additional information.
http://www.zhone.com/support/manuals/docs/AZ/MTM-A2-GB20-00.pdf
3. A CLI command to simultaneously update the IP Address, Gateway and Mask is available. The individual commands to perform these functions have been removed. The new CLI command to set all three items simultaneously is SET IP_SUB_GATE.
The IP Address, Subnet Mask, and Default Gateway can be set via Web Management, but if you choose to use Telnet (CLI), you can use the example below.
Example: SET IP_SUB_GATE 192.168.254.200 255.255.255.0 192.168.254.1
where the IP Address is 192.168.254.200, a class C Mask is used, and a Default Gateway of 192.168.254.1 is specified.
4. The ability to change a Provider base model to Subscriber mode is supported for units shipped from the factory as a Provider unit. These units may also be changed back from Subscriber to Provider mode if needed.
Please note that using this function changes the configuration. It is recommended that you clear NVRAM before changing the model type and re-configuring the unit after the change.
Note also that the ability to change from Provider mode to Subscriber mode is only available on units that were originally shipped from the factory as Provider models. In order to differentiate between model types, check for the -P or -S designation in the model number found on the bottom label of the unit.
5. A DHCP Client is now available that can set the management IP address of the device. The DHCP Client can be activated by logging into Web Management and clicking on the Management Config button or by using the CLI commands from Telnet.
The CLI commands are: SET DHCP_SETS_IP ON|OFF and SHOW DHCP_STAT
When activated, the DHCP Client is initialized at system start up. A DHCP Discover Message is sent after the SHDSL link(s) come up. In most cases this feature should be left OFF (i.e. default factory setting).
6. The ability to clear learned MAC addresses is available via a CLI command. The syntax for the CLI command is "MAC_CLEAR x" where ‘x’ is either ‘1’ or ‘ALL’. Issuing either command clears dynamic MAC addresses from both WAN and LAN ports in both upstream and downstream directions.
Note that this functionality is not yet available in Web Management, but will be provided in a future release.
7. Since version 1.01.01, the MAC Detect Trusted/Untrusted configuration option is now set to ‘OFF’ in the default configuration. This allows PCs to be connected to the unit within a 5 minute interval and not be blocked.
8. The Provider unit now resets the SHDSL link when the WAN dip-switches are changed to facilitate a data rate change.
9. The unlinked SHDSL LEDs now blink at a cadence of 10 seconds.
10. The Flood Unknown Multicast Traffic button is set to 'YES' by default to allow IGMP Multicast traffic to pass through the SHDSL link(s) by default.
11. All Provider and Subscriber units will now default with all MTM (VLAN) rules turned off (set to 'NO') to allow all VLAN tagged and untagged traffic to pass through the devices. NOTE: This is the default factory configuration. If you upgrade the code on your current ETHX-21xx unit, NVRAM will restore your current configuration, not the factory defaults.
12. The LAN and/or WAN port configuration can now be achieved using either the external dipswitches or via the Web GUI. To prevent conflicts in software vs hardware port settings, a ‘dipswitch override’ function has been added. For each set of interface types, Ethernet and SHDSL, there is a dipswitch override radio button in the web interface. This function allows remote management of the units without physically having to change the dipswitch settings. The override configuration is stored in NVRAM and is recalled over restarts and not removed until the user elects to turn off the override or clears NVRAM. If the user elects to override the dipswitch setting for one of the SHDSL ports, the override applies to the other SHDSL port (2-port units only) as well. Likewise, if the user elects to override the dipswitch setting for one of the Ethernet ports, it overrides the dipswitch setting for the other Ethernet port (if equipped). However, selecting the override for either SHDSL or Ethernet port type does not override the dipswitch settings for the other port type. For example, overriding one of the SHDSL ports overrides the other SHDSL port, but it does not override any of the Ethernet ports.
Documentation Changes
The SNMP Users Guide can be downloaded from the following site: http://www.zhone.com/support/manuals/docs/AZ/SNMP-A2-GB20-00.pdf are as follows:
Changes to the SNMP Users Guide:
- Page 1-1: Simple Network Management Protocol (SNMP): Please add “EtherXtend 2100 Series EADs” to the list of devices supported.
- Table 2-10 on Page 2-15: SDSL/SHDSL Configuration: Please update Table 2-10 to reflect the fact that for the ETHX-2100 series units, the value returned is the actual link rate (i.e. if 640 is returned, the rate is 640kbps).
