Re: J-web issue with too many redirects & phone-home

$

I was handed these switches by the client. And they are all EX2300, including the core swtich.

Also, I don't have enough privilege to download the latest J-Web version 18.1A2.

 

In the core switch, I'm getting too many redirect issues, so J-web is not usable.

In one of the access switch, I get logged out as soon as I log in. 

 

Phone-home is removed from all.

 

Please note that if I enable http, it works. So, its something with the SSL I'm guessing.


DAC compatability

Hello,

Could You help me to know if the DAC 10 G is compatabile to run on this server HPC7000 and the other side EX4600 ?hp-bladesystem-c7000-blade-enclosure-8ac.jpg

Betreff: DAC compatability

Hello,

 

EX4600 supports 10G DAC in general, you can find the complete list of supported transceivers here:

https://apps.juniper.net/hct/product/#prd=EX4600

 

If HPC7000 is working with DAC transceivers as well, you need to check in your lab, especially with the DAC transceivers you are using (original Juniper or 3rd party)

Hi HDawood,

 

Good day!!

 

The 24 small form-factor pluggable (SFP) network ports on EX4600 switches support 10-Gigabit Ethernet transceivers and direct-attach copper (DAC) cables. The switch also supplies four quad small form-factor pluggable plus (QSFP+) ports for use as uplinks. These 40-Gigabit Ethernet ports support QSFP+ transceivers, QSFP+ DAC cables, and DAC breakout cables (DACBO). Each QSFP+ port on an EX4600 switch can be configured to operate as 10-Gigabit Ethernet interface by using a breakout cable or as a single 40-Gigabit Ethernet interface. The ports on an EX4600 switch are disabled by default. You enable a port through the CLI.

 

please click the below link for better understanding

I'm using the DAC from Jujniper and need to know if it os okay to use the other side on the above server model or no ? 

 

Also I know that there are  4 QSFP  ports ,Can I use them with DAC 10 G ?

This can only be confirmed by testing the Juniper DAC cable with your HPE server, I don't think this is officially supported by HPE.

 

Also I know that there are  4 QSFP  ports ,Can I use them with DAC 10 G ?

 

10G DAC cables are SFP+ transceivers, while QSFP Ports are slots for QSFP transceivers (40G). So you cannot use 10G DAC cables with QSFP ports, as you simply cannot plug it in.

As @Luke stated, the EX4600 is a fiber switch, which means it additional SFP optics to make any interface workable.  The Base unit contains 24 SFP+ ports (accept either 1GE or 10GE optics) and 4 x QSFP 40 GE interfaces.  There are also 2 x expansion slots.  Expansion modules are either 8 x SFP+ or 4 x QSFP.  Any of the QSFP ports, either the 4 on the base or via optional expansion slot, can be channelized and provide 4 x 10GE instead of 1 x 40G.  This is done by a combination of configuration and using the proper 40GE Optic which provides for 4 x 10GE channelization.

 

The EX2200/3300/4200 (all now End of Sale) and the newer generation EX2300/3400/4300 (inlcuding MP versions) switches all have Limited Lifetime Warrenty Support (LLWS) which covers both HW and SW download support.  This is included free with any switch purchase.  The HW support is next-day ship.  What is not covered is any TAC support.  TAC support on top of LLWS can be purchased via CORE support; requires min of 10 units of any specific model.  Any other service contract such as ND (next-day arrive) or SD (same day arrive) includes TAC as well as specific HW support.

 

Please note that only switches purchased via an authorized Juniper re-sellers (i.e. non-Gray market) are allowed any level of support.  Non-authorized purchased are void of LLWS, or ability to additionally add any level of support.

I'm sure that this SKU last order was on 25/6/2020 - as per juniper website ..

 

If you could provide exact URL that would be great, as this SKU (JNP-10G-SR-8PACK) is in the Juniper July/2020 pricebook, so this SKU is not End of Sale.

 

JNP-10G-SR-8PACK  

Optics bundle with a pack of 8 QFX-SFP-10GE-SR optics for QFX and EX series products.   List Price is $8400

Note the List price for 1 x 10GE SFP is $1040 (8 x $1040 = $8400 the list price of the 8pack). FYI

 

Also for your information this was very cost effiective in case of large numbers of 10 G  fiber connections ..

OK, you are using the configurator.  I had never used Last Order date as part of a search within the configurator.  I believe this field to be inaccurate, at least as far as an actual last order date.  If you go into the configurator and search for SKU (and only checking SKU criteria box) that contains (not =) 8PACK, you'll see the various (total of 3) 8PACK SKUs.  Now go and check last order date criteria box, and you'll see today's date.  If you repeat tomorrow, the last order date will change to 7/7/2020, I believe. If you add a specific = date for that field, no matches will be returned.  I have no idea why this field is even in there.  If a SKU shows up under a search, it is orderable.

 

For any SKU to go End of Sale (which starts End of Life process) there must be an annoucement, typically via some TSB or KB.  I could not find any such announcement for 8Pack SKU.

 

Now if you search on contains 10GE-SR, you'll see an MX SKU at list price of $1050, vs $1500.  Since everything sold by Juniper through Partners is discounted, the list price often has little relevance to actual sale price.

 

I hope this may help.

thanks for explaination

 

There is a number of number of transceiver modules on the ex9200 and qfx devices..... Can I ask how to understand/check whether or not BiDi optics are installed on the devices? 

Secondly where Multi mode and Single mode optic should be used? Between managed router and switch or between managed switch and third part organisation (ISP, peer, customer)?

A couple of comments are needed for @rccpgm's post;

 

* LLWS support is always "return to factory" where you need to return the defective unit before a new one is shipped. If advanced replacement is needed an active support contract with "Next Day" (ND) or better SLA.

This pdf describes LLWS in details: https://support.juniper.net/support/pdf/warranty/990235.pdf

 

* You can still buy CORE support for on switch on LLWS - the 10 units which is referred to is the "site support" where support per unit is lower than buying support for an individual switch.

VxLan over Ipsec Internet Tunnel

Hi, I want to know if I can implement VXLAN over a Internet IPSEC tunnel.

Can I implement VXLAN over an Internet Lan 2 Lan Tunnel? What about the MTU?

Thanks

 

Re: VxLan over Ipsec Internet Tunnel

I find this idea intriguing...

 

But yes, VXLAN does add about 100bytes of overhead, so MTU would be a significant consideration.

Keep in mind that you can't control the MTU across the internet like you might in the data centre.

 

What are you trying to achieve? Is it tenant separation?

Perhaps MPLS with tunnels will be a better option?

Re: Upgrade VC-link from 40G to 100G on 4-member QFX5110

I am using switches are qfx5110-32q running Junos 17.3R1.10 flex right now.

 

In the documentation, I could find the following statement:

 

QFX5110-32Q—A 40GbE/100GbE data center access and aggregation switch, the QFX5110-32Q offers up to 32 QSFP+ ports, or 20 QSFP+ ports and four QSFP28 ports, with an aggregate throughput of 2.56 Tbps or 1.44 Bpps per switch

 

Does this means that if I go on and use 100G ports to build my virtual-chassis instead of 40G, then ports 20 to 27 will be disabled and unusable under any circumstances ? or does that depends on the Junos version running ?

 

Thanks,

Gaetan

dot1x authentication not updating when client moves between ports (EX3400)

$

We recently began deploying EX3400 as replacement for EX3000 in our MDU/MTU sites. The feature sets we're relying on are dot1x radius based authentication and private vlans (isolated); all subscribers need to be isolated.

 

With the EX3300s, as a wireless client loses association with an AP and associate with a new AP, the EX3000 will update it's forwarding table and dot1x details about the wireless device and rarely does a client know they're moving between APs.

 

Using the EX3400, the wireless client can initially associate with an AP and get online but as the client moves and associates with a newer AP, the wireless client will not get an IP address until we either manually clear the forwarding table OR the dot1x record for the client on the EX3400.

 

The wireless client will continue to reassociate itself with the new AP every 30 second or so as a retry, but the EX3400 is maintaining the old AP port as it's layer 2 port.

 

Using a port-mirror setup on the EX3400, I can see that after the wireless client associates with the new AP, DHCP Discovery packets are being being received on the switch from the wireless client. These packets are received and transmitted by the EX3400 without a vlan as our vlan assignment happens via radius and dot1x, ie. the switch is not performing a dot1x radius lookup prior to allowing the DHCP Discovery packet.

 

While on boarding the EX3400 I needed to retool some of the config syntax, it's very possible I missed something in the conversion of the configs.

 

Attached are example configurations for both the EX3300 & EX3400. (I've tried to upload them twice now, nothing saying an error.. Perhaps they need to be 'processed' first).

 

Thanks.

 

-Sean
