Symptoms: When you re-insert a PA-MC-8TE1+ port adapter in the same slot of a Cisco 7200 series
via an OIR, the serial interface may enter the Down/Down state. When you enter the shutdown
command followed by the no shutdown command on the T1 or E1 controller, the serial interface
may transition to the Up/Down state, still preventing traffic from passing.

Multiple Cisco products contain either of two authentication vulnerabilities in the Simple Network
Management Protocol version 3 (SNMPv3) feature. These vulnerabilities can be exploited when
processing a malformed SNMPv3 message. These vulnerabilities could allow the disclosure of
network information or may enable an attacker to perform configuration changes to vulnerable
devices. The SNMP server is an optional service that is disabled by default. Only SNMPv3 is
impacted by these vulnerabilities. Workarounds are available for mitigating the impact of the
vulnerabilities described in this document.
