logical tunnel interface bandwidth

[ Edited ]

Hello

working MX240 Enhanced MX SCB MPC 3D 16x 10GE

PIC 3                   BUILTIN      BUILTIN           4x 10GE(LAN) SFP+

 

it has virtual logical-systems

there is a tunnel, there bgp

 

 run show interfaces lt-1/3/0
Physical interface: lt-1/3/0, Enabled, Physical link is Up
  Interface index: 148, SNMP ifIndex: 1507
  Type: Logical-tunnel, Link-level type: Logical-tunnel, MTU: Unlimited, Speed: 100000mbps
  Device flags   : Present Running
 

so, we have grown a little traffic, respectively, he grew up in the tunnel.

BUT! Do not pump more than 16g , although he and Speed: 100000mbps

increases ping even between peering tunnel types and the speed sags of course for everyone who goes through the tunnel

 

forced speed was not set

 

run show configuration chassis fpc 1
pic 3 {
    tunnel-services;
}
 

No filters on the interface

 

just

 

unit 100 {
    encapsulation ethernet;
    peer-unit 200;
    family inet {
        address 10.10.10.1/30;
    }
unit 200 {
    encapsulation ethernet;
    peer-unit 100;
    family inet {
        address 10.10.10.2/30;
    }

 

what could be the problem? help me please

Hi,

 

Could you set the bandwithd and check?

 

[edit]
labroot@test# set chassis fpc 1 pic 3 tunnel-services bandwidth 20g

[edit]
labroot@test# show | compare
[edit chassis fpc 1]
+    pic 3 {
+        tunnel-services {
+            bandwidth 20g;
+        }
+    }

Hi,

in this configuration does not work

 

set chassis fpc 1 pic 3 tunnel-services bandwidth 20g

show log messages 

 Err: tunnel bandwidth 20000000000 not supported(1/3)

 

set chassis fpc 1 pic 3 tunnel-services bandwidth 40g

show log messages 

 Err: tunnel bandwidth 40000000000 not supported(1/3)

 

work

 delete chassis fpc 1 pic 3 tunnel-services bandwidth

Could you share "show chassis hardware" & "show configuration chassis fpc 1"

I would like to review your config, could you post config in the file.txt and attach here please?

I believe you're over subscribing bandwith per PFE as your graph.

 

PFE0 serves = x/0/x & x/1/x

PFE1 serves = x/2/x & x/3/x

 

Please refer this document:

https://www.juniper.net/documentation/en_US/junos/topics/concept/chassis-mpc-16-port-10-gigabit-ethe...

-> Supports one full-duplex 10-Gigabit Ethernet tunnel interface for each Packet Forwarding Engine

 

https://www.juniper.net/documentation/en_US/junos/topics/task/configuration/chassis-tunnel-interface...

 

Can see the same on my test node:

Feb  9 17:50:48.839  jtac-MX-re0 chassisd[18630]: Err: tunnel bandwidth 20000000000 not supported(4/3)
Feb  9 17:50:48.840  jtac-MX-re0 chassisd[18630]: Err: tunnel bandwidth 20000000000 not supported(4/3)
Feb  9 18:27:39.273  jtac-MX-re0 chassisd[18630]: Err: tunnel bandwidth 100000000000 not supported(1/2)

So just to add more info, you're limited to 10g per PFE.

1/3/x & 1/2/x  LT = 10g

1/0/x & 1/1/x  LT = 10g

 

In your case, if you want to continue on FPC1, use pic0 or pic1 for LT bandwithd.
