eliminated the possibility of transceiver hardware issue by testing with 10g Fiber loopback cable. Remarks, these two 10g fiber interface is not bonded and it is two separate 10g interface with their own ip address. One of the 10g transceiver is not blinking, it is showing link down in clish mode "show interface eth1-01", while another 10g transceiver is working. When we migrated/cut over the fiber cable from 4800 firewall to 6600 Plus quantum gateway. Meanwhile, 6600 Plus quantum security gateway has comes along with 4 Port 10GBase-F SFP+ interface card(sku:CPAC-4-10F-C) and 4x 10G SR SFP+ Transceivers(sku:CPAC-TR-10SR-C). The 4800 has a running 10G Nic card(sku:CPAC-2-10F) installed with two short-range(SR) SFP+ transceivers(sku:CPAC-TR-10SR). We are doing tech-refresh from old model 4800 firewall to model 6600 Plus quantum security gateway.
