Does anyone know how Ex4200 EX-UM-2X4SFP.works? If we can use 1G +10 mix or we can only use all port as 4x1G and 2x10G at same time?
Right now we have two fiber coming and one support 10G and other support 1G. we are trying to mix the link but not sure if it support.
Thanks in advance.
Sorry, on the 2x4SFP Uplink Module, you can mix and match 10GE and 1GE. You must set the PIC speed as first step, which is either 1GE or 10GE. From this link - :https://www.juniper.net/documentation/en_US/release-independent/junos/topics/reference/general/uplink-module-ex4200.html
NOTE: Last 2 sentances do not apply to your situation.
Now on EX4300 Uplink Module this is supported, BUT in order to get this to work you need to reset the PIC after you install the optics. You do NOT set a PIC speed on EX4300. I am trying to get the EX4300 documentation update to reflect this requirement.
Hopefully this assist you.
Can you tell us how to do that on ex4200?For e.g. if we want to use port number 2 as 1G and port number 3 as 10G. What commands we have to run to set the port speed.?
EX-UM-2X4SFP is supported in both EX4200/EX4300. Please find the Hardware Compatibility Tool.
Note: When an SFP+ uplink module or an SFP+ MACsec uplink module is operating in 10-gigabit mode:
Only the 10-gigabit ports (ports 0 and 2) are enabled.
You can use only SFP+ transceivers in those ports.
When an SFP+ uplink module or an SFP+ MACsec uplink module is operating in 1-gigabit mode:
All four ports are enabled.
You can use only SFP transceivers in all four ports.
You cannot use the hardware for both 10-gigabit mode and 1-gigabit mode simultaneously; only one at a time.
OLD Reference Topic:
Adding to the above information...
Setting the Mode on an SFP+ or SFP+ MACSec Uplink Module (CLI Procedure)
SFP+ uplink modules are supported on EX3200 and EX4200 switches, and SFP+ Media Access Control Security (MACSec) uplink modules are supported on EX4200 switches. You can use these uplink modules either for two SFP+ transceivers or four SFP transceivers. You configure the operating mode on the module to match the type of transceiver you want to use—that is, for SFP+ transceivers, you configure the 10-gigabit operating mode, and for SFP transceivers, you configure the 1-gigabit operating mode.
By default, the SFP+ uplink module operates in the 10-gigabit mode and supports only SFP+ transceivers. If you have not changed the module from the default setting and you want to use SFP+ transceivers, you do not need to configure the operating mode.
To set the operating mode of an SFP+ or SFP+ MACSec uplink module:
Change the operating mode to the appropriate mode for the transceiver type you want to use by using one of the following commands:
user@switch# set chassis fpc 0 pic 1 sfpplus pic-mode 1g
user@switch# set chassis fpc 0 pic 1 sfpplus pic-mode 10g
(SFP+ uplink module only) If the switch is running:
Junos OS Release 10.1 or later, the changed operating mode takes effect immediately unless a port on the SFP+ uplink module is a Virtual Chassis port (VCP). If any port on the SFP+ uplink module is a VCP, the changed operating mode does not take effect until the next reboot of the switch.
Note: During the operating mode change, the Packet Forwarding Engine is restarted. In a Virtual Chassis configuration, this means that the Flexible PIC Concentrator connection with the master is dropped and then reconnected.
Junos OS Release 10.0 or earlier, reboot the switch.
You can see whether the operating mode has been changed to the new mode you configured by issuing the show chassis pic fpc-slot slot-number pic-slot 1 command.
Sorry, thought I had responded to this already. My original posting had a BIG typo in it. My 1st sentance should have read:
:Sorry, on the 2x4SFP Uplink Module, you can NOT mix and match 10GE and 1GE."
As I stated, this piece of documentation is inaccurate in regards to the operation of the EX4300, although Juniper may decide to not support such a combination. This is being looked into.
The config commands mentioned to NOT apply to operation of this module in an EX4300, only for an EX4200 due to hardware differences between the 2 platforms. Basically set chassis pic mode is not a command that is associated with EX4300, only EX4200.
I can update this thread once I know more about EX4300 operation/support.
Just as another point, there might have been a typo in one of python 1st reply.
The 2x4SFP is supported on EX4200 and EX3200, NOT on EX4300. This module does NOT support a mix of speeds. You must set PIC speed on this module to either 1G or 10G - no mix.
The 4x4SFP is one of the uplink modules supported on EX4300. This module supports 4 ports of 1/10 all active at same time. The question is whether Juniper does or does not support a mix of speeds (1/10) on this module. I know it can be done - been locally tested. The issue is to get this to work, after configuration a PIC reset was required to get active. There is no config method for this module at the PIC level to set the PIC speed, as mix could/should be available.
My bad... there was a typo....
