Re: EX2200 Switch reset password for virtual chassis system.

It would require a restart to reset the password. First save the configuration to a remote system. Then schedule some downtime. Log into the the master RE at the CONSOLE! and reboot (request system reboot). Then place your finger on the space bar and look for this line:

Hit the spacebar when you you see it. 

1.“Loading /boot/defaults/loader.conf” then

  • Press the Spacebar (if you wait for the prompt- it may be too late)
  • loader> boot –s (to access single user mode)

2.Enter recovery when prompted to go into recovery mode

/bin/sh: recovery

3.Enter “edit” >Set root password

set system root-authentication plain-text-password

4.Commit the change and exit configuration mode—reboot

Okay. How do I determine which switch is the master?

Hi experts. I want your help in configuring MC-LAG on both layers i.e for QFX5110 and QFX10002. Please put me wise will this design work without any issue? I am using virtual environment on server side with converged switching modules as shown in attached diagram. Thanks

EX4200 VC port options are only 0-23 on a 48 port switch

We have a EX4200 that is connected to a 2200-c and it was never put into VC.  Before someone says something about "best practices" these two are on separate floors and will never saturate a 1GB link the VC is strictly for configuration ease.  Anyway, upon setting up the 4200 it was discovered that the only port options are 0..23.  It is a ex4200-48px and I am confused why I can't select port 47. (which is where the 2200-c is connected)  The 2200-c has the option of 0..47 and it's a little guy.  Both switches are using the best practice firmware (12.3R12-S7).  I fired up an old lab ex4200-48t and same thing.  only options 0..23 when it comes to the port settings (older 12.3 firmware)

 

User493@MAIN4200> request virtual-chassis vc-port set pic-slot 0 port ?
Possible completions:<port>               Port number (0..23)
{master:0}

I am just wonder why this is and is there a way to change it.  Thanks in advanced

QFX5200, EX3400, EX3300, EX2300, and EX2200 switches cannot be part of any mixed Virtual Chassis.

 

taken from documentation

https://www.juniper.net/documentation/en_US/junos/topics/concept/virtual-chassis-ex-qfx-series-mixed-understanding.html

 

additionally:

EX4200

2 ports on rear panel

None

Any uplink module ports (SFP, SFP+, or XFP) or through an SFP+ port on the EX4200-24F switch

Note: You cannot set a 1000BASE-T copper SFP transceiver (EX-SFP-1GE-T) connection as a VCP on EX4200 switches.

Hello all,

 

Am able to poll TX and RX laser power of a 10 Gb interface from my MX with OID 1.3.6.1.4.1.2636.3.60.1.1.1.1.5.775 and 1.3.6.1.4.1.2636.3.60.1.1.1.1.7.775.

I would like to poll the laser power of a 1 Gb interface but am not able to identify the OID. Can you please help.

Am able to see the RX power using "show interfaces diagnostics optics".

Should work with same OIDs . I just checked these OIDs and see laser power for input and output

Well that halts that project.  Thanks for that link!  Also about thre sfp!  That was going to be the next test.  Still though,  why can the ex4200 only use ports 0-23?  I guess it really doesn't matter at this point just curious

Hi,

 

Make sure your new member has following things ready :

- same JUNOS version of existing VC

- make sure you configured mixed mode on new member as well.

>request virtual-chassis mode mixed

 

- After this you can power off the old member and configure the new serial number under virtual chassis heirachy.

You may follow below link:

Hi Akushner,

I tried the same OID and changed the SNMP ifIndex accordingly but did not get any results.

I noticed that the command works for only xe-x/x/x interfaces but not for ge-x/x/x ones.

Is there any other more specific OID to get the laser power of Ge interfaces?

LAG port goes BLK DIS state after adding to VSTP

Hi,

 

I have a VSTP running between a virtual chassis (2 x QFX5110) and Cisco VSS (2 x Catalyst 6509E), the Root Bridge is on the Juniper VC and the LAG between them works just fine.

I wanted to add another Cisco switch to the Juniper VC, so I created another ae14 LAG, added ports to LAG and when I add the ae14 port to the VSTP configuration (not even attaching cables) it automatically goes into BLK (Blocking) DIS (Disable) state. Even after I do cabling it stays in that state making the LAG not working at all.

 

What I do wrong ?

 

This is my configuration of STP protocols on Juniper.

rstp {
    bridge-priority 4k;
}
vstp {
    bpdu-block-on-edge;
    interface ae0;
    interface ae14;
    vlan all {
        bridge-priority 4k;
    }
}

And this is when I added ae14 to config.

Not all VLANs which are on ae0 are on ae14 that is why ae14 is not showing up on VLAN10 for example.

 

Why ae14 is getting blocked ?? (Without even cabled).

Port role disabled simply means the interface is down. The fact that ae14 stays in that state after enabling means ae14 is not actually up, otherwise if blocked it would still be assigned some active role such as alternate. You can verify with show interfaces ae14, or show lacp interfaces ae14 if you're using lacp.

Hello,

 

I need to add the line cards of EX9200 switch for snmp monitoring. Can anyone please tell me what is the proper OID to monitor?

 

user@switch> show chassis hardware | grep EX9200 
Routing Engine 0 REV 07   750-063458   CAKxxxx          RE-S-EX9200-2X00x6
CB 0             REV 09   750-062852   CAKDxxx          EX9200-SF2
FPC 2            REV 13   750-064569   CAKFxxxx          EX9200 32x10G SFP

user@switch>

I am searching for a  proper way to find those OIDs.
