Catalyst 9300 Switches and C9300-NM-4M Module

Could someone please provide some information on Cisco Catalyst 9300 Switches (i.e. C9300-24T-E)? Does it support 10G Copper Ethernet Uplinks?

 

What's the specification of C9300-NM-4M Module? Does it include 2*10G ethernet or it supports optical SFP/SFP+ transceivers only for uplink?

 

I could hardly get those information in data sheets.

Some info found

C9300-NM-4G Module

All ports in the C9300-NM-4G module are natively GigabitEthernet and are configured GigabitEthernet1/1/1 though GigabitEthernet1/1/4. There are only four interfaces that are valid, and the other four should not be used even though they are available in the CLI.

But that is info for the C9300-NM-4G module.  I can find precious little on the C9300-NM-4M mGig module.  The Cisco 10-Gigabit Ethernet Transceiver Modules Compatibility Matrix doesn't seem to know of its existence.  And I can't find a spec sheet on it anywhere.

 

Edit: Ok duh.  It is not an SFP module, which explains why the transceiver compatibility matrix doesn't mention it.

 

 

Does anyone have POE information for the same? I assume the mGig module does have POE+ but I can't find it stated anywhere. The total POE port counts on the 9k datasheets never go beyond the 24/48 onboard ports.

I found this document, but again, not 100% clear unless you can accept the generalities as fact for this particular module.

C9300-NM-4M has 4 multigig Ethernet RJ45 ports.

Its Support SFP-10G-T-X =?

Is it confirmed that the C9300-NM-4M is capable of handling four 10gb connections? The documentation talks about how mGig ports support a range of speeds up to 10gb/s. But it doesnt say that this card is capable of driving four 10gb ports.

These are line rate switches, regardless of the modules you use. The switch runs at line rate and the modules run at line rate.

Multigigabit Ethernet Ports

The Multigigabit (mGig) Ethernet ports can be configured to auto-negotiate multiple speeds on switch ports. The ports support 100 Mbps, 1 Gbps, 2.5 Gbps, and 5 Gbps speeds on Category 5e (Cat5e) cables, and up to 10 Gbps over Category 6 (Cat6) and Category 6A (Cat6A) cables up to a maximum of 100 m. 10Gbps over Cat6 cable is limited for distances up to 55 m. For 10GBASE-T, Cat6a can support up to 100 m when transmitting 10Gbps.

Those are the supported rates, but the switch doesn't know the grade or length of the cable attached to it.  It will negotiate the fastest rate that it can, and sometimes it is more than the cable can handle and it will end up taking errors.
