SYNOPSIS

# Let SNMP::Info determine the correct subclass for you.
my $ciscostats = new SNMP::Info(
                         AutoSpecify => 1,
                         Debug       => 1,
                         DestHost    => 'myswitch',
                         Community   => 'public',
                         Version     => 2
                       )
   or die "Can't connect to DestHost.\n";

my $class = $ciscostats->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";

DESCRIPTION

SNMP::Info::CiscoStack is a subclass of SNMP::Info that provides an interface to the CISCO-STACK-MIB. This MIB is used across the Catalyst family under CatOS and IOS.

Use or create in a subclass of SNMP::Info. Do not use directly.

Inherited Classes

none.

TABLE METHODS

Interface Tables

$stack->i_physical()

Returns a map to IID for ports that are physical ports, not vlans, etc.

$stack->i_type()

Crosses p_port() with p_type() and returns the results.

Overrides with ifType if p_type() isn't available.

$stack->i_duplex()

Returns reference to hash of iid to current link duplex setting.

First checks for fixed gigabit ports which are always full duplex. Next, if the port is not operational and reported port duplex (portDuplex) is auto then the operational duplex can not be determined. Otherwise it uses the reported port duplex (portDuplex).

$stack->i_duplex_admin()

Returns reference to hash of iid to administrative duplex setting.

First checks for fixed gigabit ports which are always full duplex. Next checks the port administrative speed (portAdminSpeed) which if set to autonegotiate then the duplex will also autonegotiate, otherwise it uses the reported port duplex (portDuplex).

$stack->i_speed_admin()

Returns reference to hash of iid to administrative speed setting.

portAdminSpeed

$stack->set_i_speed_admin(speed, ifIndex)

Sets port speed, must be supplied with speed and port C<ifIndex>

Speed choices are 'auto', '10', '100', '1000'

Crosses $stack->p_port() with $stack->p_duplex() to
utilize port C<ifIndex>.

Example:
my %if_map = reverse %{$stack->interfaces()};
$stack->set_i_speed_admin('auto', $if_map{'FastEthernet0/1'})
    or die "Couldn't change port speed. ",$stack->error(1);

$stack->set_i_duplex_admin(duplex, ifIndex)

Sets port duplex, must be supplied with duplex and port C<ifIndex>

Speed choices are 'auto', 'half', 'full'

Crosses $stack->p_port() with $stack->p_duplex() to
utilize port C<ifIndex>.

Example:
my %if_map = reverse %{$stack->interfaces()};
$stack->set_i_duplex_admin('auto', $if_map{'FastEthernet0/1'})
    or die "Couldn't change port duplex. ",$stack->error(1);

$stack->p_rx_flow_control()

Can be either on off or disagree

"Indicates the receive flow control operational status of the port. If the port could not agree with the far end on a link protocol, its operational status will be disagree(3)."

portOperRxFlowControl

$stack->p_tx_flow_control()

Can be either on off or disagree

"Indicates the transmit flow control operational status of the port. If the port could not agree with the far end on a link protocol, its operational status will be disagree(3)."

portOperTxFlowControl

$stack->p_rx_flow_control_admin()

Can be either on off or desired

"Indicates the receive flow control administrative status set on the port. If the status is set to on(1), the port will require the far end to send flow control. If the status is set to off(2), the port will not allow far end to send flow control. If the status is set to desired(3), the port will allow the far end to send the flow control."

portAdminRxFlowControl

$stack->p_tx_flow_control_admin()

Can be either on off or desired

"Indicates the transmit flow control administrative status set on the port. If the status is set to on(1), the port will send flow control to the far end. If the status is set to off(2), the port will not send flow control to the far end. If the status is set to desired(3), the port will send flow control to the far end if the far end supports it."

Data Munging Callback Subroutines

$stack->munge_port_status()

Munges binary byte describing each port into ascii, and returns an ascii list separated by spaces.
