3.2.1.1 Configuring Tunnel Management
The Tunnel Management feature allows you to encapsulate in-band management and/or SOAM
and PM/SAM in a single service provider tag (S-Tag) on a specified port. An S-Tag is compliant
with IEEE 802.1ad, with an Ethertype of 0x88A8.
NOTE: If an S-Tagged tunnel is being implemented with the VLAN rules, then
ingress C-tagged packets cannot exceed 9946 payload bytes in length,
because the resultant frame would exceed the system maximum of
10,000 bytes.
The Tunnel Management screen (Figure 3-4) displays the S-Tagging attributes for Management
and Service OAM and PM/SAM traffic.
To configure Tunnel Management, type the number of the attribute you want to configure and
press Enter. Press the Space bar to select Yes or No. Press Tab to move from User to Network
port. Press Enter the accept the setting.
1. Tunnel SOAM and PM/SAM Traffic Select Yes or No to enable or disable S-Tagging for
SOAM and PM/SAM packets on the User or Network port. Depending on the targeted
application, this feature can be used to stack SOAM and PM/SAM across a network cloud
with an S-Tag. You must enable this option if your application uses a Test IP or Auxiliary
IP to initiate test packets (examples are PM/SAM/CPM, Ping, and Latency Jitter). Tunnel
PM/SAM traffic covers the traffic to and from the Test IP address and the Aux IP address.
When PM/SAM traffic is using the Manager IP address, it is tunnelled or not based on the
setting of Tunnel In-band Management Traffic.
2. Tunnel In-band Management Traffic Select Yes or No to enable or disable S-Tagging
for in-band management traffic on the User or Network port. In-band management
includes all traffic used to manage the NID using the management IP address, such as
Telnet/SSH, SNMP, and any diagnostic tools that uses the management IP address. You
must enable this option if your application uses a Management IP to initiate test packets.
3. Tunnel S-Tag VLAN ID Specifies the S-Tag VLAN ID and priority.
4. Duplicate C-Tag Priority If set to Yes, indicates that the value of P-bits for the outer tag
(S-Tag) is copied from the inner tag (C-Tag).
