ESM/VCPM MODULE

ANDE Module

Introduction ANDE (advanced network data encryption card) supports IPSec and hardware expedited IP data packet encryption, thus providing encryption with high performance and reliability.

■Installed with an ANDE card, the main board of your router can implement VPN with encryption provided by the ANDE card in addition to IP packet forwarding.

Interface Attributes The following table describes the interface attributes of the FIC-HNDE.

Table 171 Interface attributes of the ANDE module

Attribute	Description
Protocol supported	IPSec
IPSec concurrent tunnels	100 (implemented through software)
Hardware algorithm	key algorithm (DES, 3DES, AES, QC5,
	Blowfish, Cast-128 and SkipJack)
	Authentication algorithm
	(HMAC-MD5-96, HMAC-SHA-1-96)

Interface LEDs There is no LED on the ANDE module. Display of the status of the module is implemented through the ESM interface LED on the main board of the router.

The following table describes the LEDs on the panel.

Table 172 Description of the LEDs on the panel

LED	Description
ESMx	Green: ANDE card is in the slot and is operating normally.
	Yellow: ANDE card is in the slot but cannot be accessed by the router.
Note:

x means the number of the slot the ESM LED is in.

Installing/Removing ANDE card should be installed on the main board and the ESM slot on the MSCA ANDE Card card of MSR 20/30/50 router. The board that provides ESM slots is referred to

hereafter as mother board. Suppose the mother board is uninstalled and put on the workbench.

Removing ANDE card
