Safety Notice Regarding UHD100T32 Chassis
WARNING: In order to prevent accidental injury to personnel, do not leave the QSFP28 transceiver cages uncovered on the UHD100T32 chassis. When transceivers
are not installed, port end caps must be used. The metal edge of the transceiver cage is SHARP. To avoid injury, ALWAYS keep the open transceiver cage covered with the end cap.
Contact ISG Technical Support to obtain replacement end caps (part number 503-0012).
UHD 1.1 features
| UHD100T32 |
| UHD now supports adding the VXLAN header to data plane traffic configuration. |
| Transmit equalization settings can be modified via the admin CLI. Refer to the getting started guide for the CLI commands and usage. |
| FEC Statistics such as corrected and uncorrected codewords are now available in UHD port statistics view. |
| Configurations up to 16 flow groups per 100G/40G port are supported in UHD 1.1. For 10G/25G, 4 flow groups are supported per port. For 50G, 8 flow groups are supported per port. |
| Up to 4 concurrent users can run test in a UHD100T32 chassis. |
(None)
| Bug Number |
Notes |
| 1547757 |
IPv6 Management is not working correctly in UHD. Only IPv4 management is available at the moment. Using IPv6 management will lead to the UHD application not working correctly.
|
| 1550259 |
The admin CLI password will get reset to the default password on system reboot.
|
Control Plane Capture
| Bug Number |
Notes |
| 1542963 |
In rare instances, control plane may fail after long duration captures of more than 2 hours.
|
| 1550235 |
The REST API for control plane capture may take up to 7 minutes.
|
Flow Tracking
| Bug Number |
Notes |
| 1546078 |
Starting traffic items without 'Flow Tracking' enabled will bring down protocol sessions. The workaround for this is to enable 'Flow Tracking' on all traffic items.
|
Performance
| Bug Number |
Notes |
| 1550867 |
For packet encapsulations of more that 2 headers, line rate may not be achieved for very small packet sizes.
|
Rates
| Bug Number |
Notes |
| 1546659 |
When running certain traffic scenarios the transmit rate may be off by more than 0.1%. The worst case deviation is 0.3% vs the desired rate.
|
Statistics
| Bug Number |
Notes |
| 1545378 |
Intermittently, user defined statistics from the drill down action will not be created or will not show proper statistics.
|
| 1550875 |
When running 64B traffic at line rate with a single 25G/10G port pair, the real time traffic delta may be positive. This delta will be zero once traffic stops given there is no loss in the DUT.
|
Transceiver link
| Bug Number |
Notes |
| 1542992 |
If links are down after switching into an invalid speed mode for a transceiver, that transceiver may need to be removed and inserted back.
