Transition Networks ION x222x / x32xx User Guide 802.1p Prioritization The ability to send traffic to various prioritization queues based on the 802.1q VLAN Tag priority field. (AKA, CoS. Standard: IEEE 802.1p.) 802.1q IEEE 802.1Q, or VLAN Tagging, is a networking standard allowing multiple bridged networks to transparently share the same physical network link without leakage of information between networks. IEEE 802.1Q (aka, dot1q) is commonly refers to the encapsulation protocol used to implement this mechanism over Ethernet networks. IEEE 802.1Q defines the meaning of a VLAN with respect to the specific conceptual model for bridging at the MAC layer and to the IEEE 802.1D spanning tree protocol. 802.1Q VLAN 802.1Q is a standardized way of segmenting and distributing VLAN information. Switches that support 802.1Q can recognize and forward, a tag packet upon egress. See also VID, dot1Q, IEEE 802.1Q. Contrast "PVLAN".) 802.3 The x323x NIDs support both Link layer OAM (LOAM, per IEEE 802.3-2005 Clause 57) and Service layer OAM (SOAM, per IEEE 802.1AG and Y.1731).Compare to LOAM. ACL (Access Control List) A set of data that informs a computer's operating system which permissions, or access rights, that each user or group has to a specific system object, such as a directory or file. Each object has a unique security attribute that identifies which users have access to it, and the ACL is a list of each object and user access privileges such as read, write or execute. Address An IPv6‐layer identifier for an interface or a set of interfaces. Anycast address In IPv6, an identifier for a set of interfaces (typically belonging to different nodes). A packet sent to an anycast address is delivered to one of the interfaces identified by that address (the "nearest" one, according to the routing protocol's measure of distance). AES (Advanced Encryption Standard) A privacy protocol; one of two encryption algorithms used for ION system data privacy. AES is a symmetric‐key encryption standard adopted by the U.S. government. The standard comprises three block ciphers, AES‐128, AES‐192 and AES‐256, adopted from a larger collection originally published as Rijndael. Each cipher has a 128‐bit block size, with key sizes of 128, 192 and 256 bits, respectively. AES ciphers were analyzed extensively and are now used worldwide (as was its predecessor, DES). AES was announced by NIST as U.S. FIPS PUB 197 (FIPS 197) in 2001 after a 5‐year standardization process. AES was implemented as a Federal government standard in 2002 after approval by the U.S. Secretary of Commerce. AES is available in many different encryption packages. See also "DES". A 33472 Rev.
