I am considering the use of the switch WS-C2960S-24TS-L as a standard access switch for a large organization.
This means standardized architecture and following the best practices.
They used switches with dual-purpose uplinks before.
- 24 x Ethernet 10/100/1000 ports
- 4 x 1GbE SFP uplinks
If I want to connect this access switch to a distribution switch, what would be better?
- Using one of the 24 "downlinks" as an "uplink"... is it really a good practice? I mean, is it an issue? Isn't there any risk?
- Using a 1000BASE-T Ethernet SFP module (GLC-T=)
PS: Also, what do you think about 10GbE uplinks at the access layer? Isn't it a bit too much?
My suggestion is to use the Gigabit ports as dual uplinks to your distribution switches pair and use the Ethernet ports for access ports. Although you could use any port as uplink, the Gigabit ones are designed to be used as uplinks, what will provide consistency to your network design.
The use of 10Gb uplinks from access to distribution is usually deployed in Data Centers and not on the Campus Enterprise.
Hope this helps.
