Problem Description

OSN2500 SSN1EMS4, SSN1EGS4 application is also more and more, and my company's version of these 2 boards develops very quickly, the function is constantly enhanced, and the function of different versions of the function is very different, so that the difference between the configurations is also very big, so it is very important to configure correctly.

Configuration Notes:

1. Only EPL services support flow control;

2. EMS4 and EGS4 single boards only support the inner loopback of PHY, and do not support other loopbacks;

3. EMS4 and EGS4 single boards configured with BPS and PPS functions cannot be docked;

4, EMS4, EGS4 single-board maximum packet length settings only even number to play a role, if set to an odd number will be larger than the actual settings of 1.

5, single-board test frame R4, R6 version supports GFP and MAC bearer mode. Subsequent versions support GFP bearer mode.

6, the single board only supports 2VBs, the attributes of the 2VBs must be the same, i.e., either both are pure bridges or both are virtual bridges, not one bridge is a pure bridge and the other is a virtual bridge.

7, BPS, PPS protection: full-duplex mode does not support the protection of single-fiber failure of the sending fiber, the FE port only supports 100mfull.

8、In the same multicast and broadcast domain, if the VB hooks up more than 48 ports, it will result in the sending rate of multicast and broadcast messages not reaching the line speed.

9, R7 and above versions added intelligent power management, single board to go online need to first request the host to enter the high power consumption. If the single board and the host do not match, it may lead to the single board can not go online, such as the R7 version of the single board software plugged into the use of R4 host on the network elements, the R4 host will not respond to the single board request to enter the high power request, resulting in the R7 version of the single board can not be started under the R4 host.

10, OSN2500 SSN1EMS4, SSN1EGS4 single-board minimum support for 64-byte packet length, and R6C02B012SP03 before the version does not do the short packet make-up function, and other devices docking, there may be a docking device to receive too small packets (less than 64-byte messages) resulting in loss of packets; if the above problems occur , in the replacement of If the above problem occurs, you need to hard reset the board after replacing R6C02B012SP03 and subsequent versions that support short packet completion.
