Description
ESP with the MD5 (HMAC variant) authentication algorithm.
ESP with Advanced Encryption Standard (AES). Encryption with a 128-bit key
ESP with AES. Encryption with a 192-bit key.
ESP with AES. Encryption with a 256-bit key.
ESP with the SHA (HMAC variant) authentication algorithm.
IP compression with the LZS algorithm.
The following are examples of permissible transform combinations:
ah-md5-hmac
•
esp-des
•
esp-3des and esp-md5-hmac
•
ah-sha-hmac, esp-des, and esp-sha-hmac
•
comp-lzs
•
A previously configured Serial interface or subinterface will be read-only and will
not be configurable in the following cases:
The interface is configured with the encapsulation ppp and
•
ppp multilink ... Cisco IOS commands.
The interface is configured with the encapsulation hdlc and ip address
•
negotiated commands.
The interface is part of a SERIAL_CSUDSU_56K WIC.
•
The interface is part of a Sync/Async WIC configured with the
•
physical-layer async command.
