Two gsrs connected by one 2.5G POS is used to carry about 2.3G traffice. The 2.5G is very congested and can not work well so that I add another 2.5G pos between two GSRs. But I check the new link has lost many packet by testing with directly ping.I check the interface and find many input errors and CRC.How to troubleshooting?
Thanks
