qlge 0000:1a:00.1: ql_process_mac_rx_page: Receive error, flags2 = 0x5d The above error means, packet was received with CRC error which also has TCP and Promiscuous bit set. Please check cables, SFP's and switch ports. Thanks, Jitendra
Thanks for your help. Replacing SFP cable helped, logs are clear now. Ticket can be closed.
