10G / 25G cross-compatibility : r/networking

16 votes, 20 comments. true I usually let the transceivers dictate bandwidth in my network (I believe that qualifies as “best practice”). That said it was a big talking point when SFP28 first came out that they

Solved: E810-XXVDA2 unable to establish link at 25G

If I use a SFP28 DAC cable between the switch and the E810 nic, then the connection establishes at 25G immediately. However, when I use

Will 25G SFP work in 10G？

In general, 25G SFP (Small Form-factor Pluggable) modules are not guaranteed to work in 10G SFP ports. The primary reason for this is that 25G modules typically operate at a higher data

Port-channel and speed nonegotiate (25G vs 10G)

A particular server provides 10G links (dual) that are currently connected (port-channel) to a Cisco device (9500-40X). My task is to migrate the server to the brand new switch C9500-48Y4C
