*PoE
The 48x1G RJ45 ports on the front panel of N3248P-ON support PoE, but N3248TE-ON doesn't support PoE, the maximum output power supported is up to 30 watts. See the link /wiki/spaces/PicOS44sp/pages/4296480 for PoE command reference, the following PoE commands are not supported on N3248P-ON:
- set poe interface max-power
- set poe interface mode
- set poe interface threshold-mode
- set poe power management-mode
1G RJ45 Port
The 10/100/1000M RJ45 ports don’t support setting of the force speed by using set interface gigabit-ethernet<interface-name> speed <speed> command, but only supports auto-negotiation mode. Together with the optional set interface gigabit-ethernet <interface-name> auto-speeds <auto-speed> command, user can manually specify the auto-negotiation rate range.
25GbE SFP28 Port
Ports Te-1/1/1, Te-1/1/2, Te-1/1/3 and Te-1/1/4 are a group of ports, you should manually configure the port speed for these four ports by using the set interface gigabit-ethernet speed command before inserting an optical module. When configuring the rate, the supported port rates are 25 Gbit/s, 10 Gbit/s, and 1 Gbit/s. The four ports can be configured with the same port rate or different rate. When configured at different port rates, 10G and 1G can coexist, but 25G cannot coexist with other rates. The following table gives several cases of speed setting for this group of ports.
te-1/1/1 | te-1/1/2 | te-1/1/3 | te-1/1/4 | Allowed or not allowed | |
case #1 | 10 G | 10G | 10G | 10G | ✓ |
case #2 | 1G | 1G | 1G | 1G | ✓ |
case #3 | 25G | 25G | 25G | 25G | ✓ |
case #4 | 1G | 10G | 1G | 10G | ✓ |
case #5 | 25G | 1G | 25G | 25G | X |
case #6 | 25G | 10G | 25G | 10G | X |
case #7 | 25G | 1G | 10G | 25G | X |
Note: If the port rate is set to 25 Gbit/s, but a 10 Gbit/s optical module is inserted, the port cannot go up.
HiGig2 stacking ports
N3248P-ON has one slot for QSFP module at the rear side which can be plugged in 2 x 100G QSFP modules. The port numbers of the QSFP module are Xe-1/1/1 and Xe-1/1/2. They can be used as normal 100G QSFP28 ports.
