Dell Z9100 ON Switch - shawfdong/hyades GitHub Wiki
The Dell Networking Z9100-ON is a 10/25/40/50/100GbE top-of rack (ToR) fixed switch purpose-built for applications in high-performance data center and computing environments[1]. Dell Z9100-ON is based on the Broadcom Tomahawk ASIC (BCM56960)[2]. It has 32x 100GbE (QSFP28) ports and 2x 10GbE (SFP+) ports. The total full duplex throughput of the switch is 6.4 Tbps.
Dell Networking Z9100-ON seems to be running DNOS (Dell Networking Operating System ) 9.x, which is a further development of the FTOS (Force10 Operating System).

A 100GbE (QSFP28) port can be downgraded to 40GbE (QSFP+), e.g.:
Dell#configure Dell(conf)#interface hundredGigE 1/30 Dell(conf-if-hu-1/30)#shutdown Dell(conf-if-hu-1/30)#exit Dell(conf)#stack-unit 1 port 30 portmode single speed 40G Warning: Enabling Single mode on stack-unit 1 port 30. Please verify whether the configs related to interface Hu 1/30 are cleaned up before proceeding further. [confirm yes/no]:yes Single mode is enabled on stack-unit 1 port 30 Dell(conf)#interface fortyGigE 1/30/1 Dell(conf-if-fo-1/30/1)#no shutdown Dell(conf-if-fo-1/30/1)#mtu 9416 Dell(conf-if-fo-1/30/1)#endNote that the interface has changed from hundredGigE 1/30 to fortyGigE 1/30/1; and the MTU (Max Frame Size) is set to 9416 for jumbo frame.
We can split a 100GbE (QSFP28) port to 4x 25GbE (SFP28) ports, using a QSFP28 to 4xSFP28 breakout cable, e.g.:
Dell#configure Dell(conf)#interface hundredGigE 1/20 Dell(conf-if-hu-1/20)#shutdown Dell(conf-if-hu-1/20)#exit Dell(conf)#stack-unit 1 port 20 portmode quad speed 25G Warning: Enabling Quad mode on stack-unit 1 port 20. Please verify whether the configs related to interface Hu 1/20 are cleaned up before proceeding further. [confirm yes/no]:yes Quad mode is enabled on stack-unit 1 port 20then the interface hundredGigE 1/20 is turned to 4 interfaces: twentyFiveGigE 1/20/1 – twentyFiveGigE 1/20/4.
