8.12.9 Security
Note Gigabit Ethernet is not supported on Port 9 and Port 10. Port 11 and Port 12 support only OC-3/STM-1
or OC-12/STM-4.
Additionally, the following guidelines apply to the ADM-10G card:
• The trunk port supports OC-192/STM-64 and OTU2.
• The Interlink port supports OC-192/STM-64.
• Up to six ADM-10G cards can be installed in one shelf.
• The card can be used in all 15454-SA-ANSI and 15454-SA-HD shelves as well as ETSI ONS 15454
standard and high-density shelves.
• A lamp test function can be activated from CTC to ensure that all LEDs are functional.
• The card can operate as a working protected or working nonprotected card.
• In a redundant configuration, an active card hardware or software failure triggers a switch to the
standby card. This switch is detected within 10 ms and is completed within 50 ms.
• ADM-10G cards support jumbo frames with MTU sizes of 64 to 10,000 bytes; the maximum is
9,216.
• After receiving a link or path failure, the ADM-10G card can shut down only the downstream
Gigabit Ethernet port.
Note In ADM-10G cards, the Gigabit Ethernet port does not support flow control.
8.12.9 Security
The ADM-10G card that an SFP or XFP is plugged into implements the Cisco Standard Security Code
Check Algorithm that keys on vendor ID and serial number.
If a PPM is plugged into a port on the card but fails the security code check because it is not a Cisco
PPM, a minor NON-CISCO-PPM alarm is raised.
If a PPM with a nonqualified product ID is plugged into a port on this card—that is, the PPM passes the
security code as a Cisco PPM but it has not been qualified for use on the ADM-10G card, a minor
UNQUAL-PPM alarm is raised.
8.12.10 Protection
The ADM-10G card supports 1+1 and SONET path protection and SDH SNCP protection architectures
in compliance with Telcordia GR-253-CORE, Telcordia GR-1400-CORE, and ITU-T G.841
specifications.
8.12.10.1 Circuit Protection Schemes
The ADM-10G card supports path protection/SNCP circuits at the STS/VC4 (high order) level and can
be configured to switch based on signal degrade calculations.
