pc-x/x/x interface configuration

[ Edited ]

Hi,

I just insert retrun PIC (PE-4GE-TYPE1-SFP-IQ2) at lab m7i and has pc-0/3/0 interface.

Try to delete pc-x/x/x interface but cannot.

 

juniper@rmatest-m7i# delete interfaces pc-0/3/0
warning: statement not found

[edit]
juniper@rmatest-m7i# run show interfaces pc-0/3/0 brief
Physical interface: pc-0/3/0, Enabled, Physical link is Up
  Type: PIC-Peer, Link-level type: PIC-Peer, MTU: Unlimited,
  Clocking: Unspecified, Speed: 800mbps
  Device flags   : Present Running
  Interface flags: Point-To-Point SNMP-Traps Internal: 0x4000

  Logical interface pc-0/3/0.16383
    Flags: Point-To-Point SNMP-Traps Encapsulation: PIC-Peering
    inet  10.0.0.1         --> 10.0.0.19

Hi pynoc,

 

It is an interface that is associated with each installed IQ2 type PIC.  It is required and it cannot be deleted so please don't try :-)  Just ignore it.  It should be there.

Re: pc-x/x/x interface configuration

Thanks,

I forget :smileyvery-happy:

I am trying to take CoS advantage with IQ2 PIC.

Also I want to see more product detail with PE and PB 8 port. 

Do you have any suggest URL?

 

Thanks again...

Hi pynoc,

 

Pure product information on IQ2 PICs can be found at http://www.juniper.net/products/modules/100163.pdf.

 

CoS information is available in the class-of-service section of our online documentation.  IQ2 PICs have some particular extra functionality not available on other PICs (e.g. hierarchical shapers) while having certain limitations (only one high priority queue) so you need to look carefully when deciding on IQ2 PICs.  They also have oversubscription within individual PICs.

 

Rgds,

Re: pc-x/x/x interface configuration

Hi, can you pls point to documentation which explains the use of pc-*/*/* interface? Is it used for hiearchicial shapers?

Cheers

Hi Shiv,

 

No, the pc interface is not usable at all.

 

It is just an 'internal' interface, used by Juniper router for booting/managing IQ PICs.

It is automatically created and used as soon as you bring online an IQ PIC, but cannot be configured and should not be touched.

 

Hierarchical shaping is configured (on interfaces which support it) referring directly to ge-x/y/z

 

Please see here for details:

I hope it helps,

 Saverio
