ENTERASYS-8021X-REKEYING-MIB.mib object view, vendor Enterasys-Networks
Introduction
Most network devices and programs ship with so-called MIB files to describe the parameters and meanings (i.e.: friendly names) which are available for monitoring via SNMP.
ActiveXperts Network Monitor 2024 can import vendor-specific MIB files, so it can be used to monitor specific OID's (Object Identifiers).
This way, you can monitor your devices, computers, etc. by selecting your relevant OID's by name.
ActiveXperts Network Monitor 2024 can import MIB file ENTERASYS-8021X-REKEYING-MIB and use it to monitor vendor specific OID's.
ENTERASYS-8021X-REKEYING-MIB file content
Object view of ENTERASYS-8021X-REKEYING-MIB:
| Scalar Object |
| etsysDot1xRekeyConfigEntry |
.1.3.6.1.4.1.5624.1.2.17.1.1.1.1 |
|
Each conceptual row holds encryption key configuration
information for the Authenticator PAEs associated with one
port.
|
| Tabular Object |
| etsysDot1xRekeyEnabled |
.1.3.6.1.4.1.5624.1.2.17.1.1.1.1.1 |
|
Determines how an access point selects radio encryption
keys.
If the selected port/Authenticator PAE does not support
the EAPOL-Key feature (e.g., because radio keys are not
applicable to Ethernet ports), this object's value will
be FALSE and attempts to write TRUE will fail.
Normally, if radio keys are present, the manager enters
them into the access point through some manual process.
The manager or the users may also need to configure the
keys into each laptop (access points can distribute the
keys automatically to 802.1x EAP-TLS clients). However
laptops get keys, the keys remain static until somebody
goes to the trouble of changing them. If the keys stay
unchanged for long periods, this can make it easier for
a determined attacker to launch a cryptographic attack.
When rapid rekeying is enabled, an access point ignores
its manually-set keys. It generates pseudo-random keys
on a periodic basis, using IEEE 802.1x key distribution
to deliver the keys to new and current clients.
Do not enable rapid rekeying unless ALL of your clients
support IEEE 802.1x and an authentication method (e.g.,
EAP-TLS) that supports key distribution.
Before enabling rapid rekeying, make sure that you have
set 'dot1xAuthKeyTxEnabled' to TRUE. Changing the keys
without telling any of the clients about the changes is
not a very useful mode of operation.
|
| etsysDot1xRekeyPeriod |
.1.3.6.1.4.1.5624.1.2.17.1.1.1.1.2 |
|
When rapid rekeying (periodic changing of radio keys) is
enabled, the value of this object determines the period,
in seconds, between key changes.
|
| etsysDot1xRekeyLength |
.1.3.6.1.4.1.5624.1.2.17.1.1.1.1.3 |
|
Determines the number of bits/bytes used in the
encryption keys. Currently supports either 128-bit
(16-octet) encryption keys or 40-bit (5-octet)
encryption keys.
|
| etsysDot1xRekeyAsymmetric |
.1.3.6.1.4.1.5624.1.2.17.1.1.1.1.4 |
|
Determines the association between the supplicant and
authenticator transmit keys.
If true(1), the authenticator and supplicant will use
different encryption keys in order to transmit data.
If false(2), the authenticator and supplicant will use
a single key pattern to encrypt the transmitted data.
|
| Table |
| etsysDot1xRekeyConfigTable |
.1.3.6.1.4.1.5624.1.2.17.1.1.1 |
|
A table that contains encryption-key-related configuration
objects for ports on which Authenticator PAEs can run.
|
| Object Identifier |
| etsys8021xRekeyingMIB |
.1.3.6.1.4.1.5624.1.2.17 |
|
This MIB module defines a portion of the SNMP enterprise
MIBs under Enterasys Networks' enterprise OID pertaining to
IEEE 802.1x authentication.
This MIB is designed to supplement and be used in connection
with the standard IEEE 802.1x MIB.
It provides configuration controls for Enterasys Networks'
rapid rekeying feature -- a feature that enhances wireless
LAN security by changing the network's radio keys on a
regular basis.
