Configuring SAToP Emulation on Channelized OC3/STM1 CE PICs

This configuration example applies to the mobile backhaul application shown in Figure 40.

Set the Encapsulation Mode

Channelized OC3/STM1CE PICs can be configured with SAToP encapsulation at the PE router:



[edit]
interfaces {


coc3|cstm1-x/y/x {
encapsulation 
<
		satop>
	;
unit 
<
		0>
	;
}


}

There is no need to configure any cross-connect circuit family since it will be automatically created for the above encapsulation.

Setting Payload Size and Octet Aligned Mode

You can configure the payload size and octet-aligned mode on the PE-CE bound interface, as follows:



[edit]
interfaces {


 coc3|cstm1-x/y/x {


satop-options { 
payload-size 
<
		n>
	# Payload-size in integer
number of bytes;
octet-aligned # Octet-aligned is a toggle, not setting
equates to no-octet-aligned;
........
}


}


}

Configuration for the TDM pseudowire at the PE uses the existing Layer 2 circuit infrastructure:



neighbor a.b.x.y {


interface coc3-x/y/z.0 {
virtual-circuit-id 1;
}


}

After the CE-bound interfaces (for both PEs) are configured with proper encapsulation, payload size, and other parameters, the two PEs will try to establish a pseudowire with PWE3 signaling extensions. The following pseudowire interface configurations will be disabled or ignored for TDM pseudowires:

ignore-encapsulation
mtu

The supported pseudowire types are:

0x0011 Structure-Agnostic E1 over Packet (SAToP)
0x0012 Structure-Agnostic T1 (DS1) over Packet (SAToP)

When the local interface parameters match the received parameters, and the pseudowire type and control world bit are equal, the pseudowire is established.

For detailed information about PICs, see the PIC Guide for your router.
