HP Virtual Connect for Cisco Network Administrators (version 1.2x) page 44
The monitor session must be configured with at least one ‘monitored port’ and a single ‘analyzer
port’. The ‘monitor port’ list is the list of server downlinks whose traffic will be mirrored. The ‘analyzer
port’ is the VC uplink port that the network analyzer is connected to. VC will mirror the traffic from
the monitored ports to the analyzer port.
A Port Monitoring session can mirror the traffic for up to 16 server downlinks to the analyzer port. Any
VC uplink can be defined as the analyzer port and any server downlinks can be selected as the
monitored port. There is no VC Ethernet module dependency.
Lastly, the Administrator can choose the direction of the traffic to mirror – to the server, from the
server, or both.
Logging
Virtual Connect provides a local system log that records VC domain events and timestamps. The
local system log is not editable and does not permit manual clearing (for security purposes). The log
is circular and once the buffer is full, older entries are removed.
Centralized User Access Control (LDAP)
In the current version of VC firmware, TACACS+ and RADIUS are not supported for centralized user
access control. VC currently only supports Lightweight Directory Access Protocol (LDAP).
Please consult the Virtual Connect User Guide for LDAP implementation details.
Cisco Discovery Protocol (CDP)
Cisco Discovery Protocol (CDP) is a Cisco proprietary protocol used to exchange device identity
and capability information between two directly connected Cisco devices. CDP allows each Cisco
device to display, for the administrator, a table showing the identity and capability of other directly
connected Cisco devices. One of the primary uses of this information is for troubleshooting
purposes.
Virtual Connect does not support CDP. VC does support the industry standard protocol called Link
Layer Discovery Protocol (LLDP) by default. LLDP is functionally equivalent to CDP, although the two
protocols are not compatible. Many Cisco switches support LLDP. The global configuration
command “lldp run” and the interface commands “lldp transmit” and “lldp receive” are used to
enable LLDP on a Cisco switch that supports the protocol. The exec command “show lldp
neighbors” displays LLDP neighbor information to the Cisco switch console.
Virtual Connect provides the LLDP neighbor information for each VC uplink at the bottom of the
statistics page for each port.
