Reported for VPN roots
Description number of Internet Key Exchanges (IKE) failures
Units failures per hour
Default
thresholds
minimum 0–maximum 0
Points to check VPNs below this root
Reported for physical or virtual interfaces (DLCI, VP, or VC) of any device, ToS roots, ToSs,
VLAN roots, VLANs, VPN roots, or VPNs
Description WAN or serial interfaces receive data as a series of bits. The transmission speed
depends on the characteristics of the line connected to the interface. This line can
be a leased line or the input point on a switching network, such as Frame Relay,
ATM, or X.25.
LAN interfaces have a fixed bandwidth of 10 or 100 Mbps. In the case of routers,
numerous machines on the LAN often share this bandwidth. Thus, the traffic
received by a router rarely reaches this limit. In the case of LAN switches, some of
which allow for full-duplex connections, the input rate can reach the theoretical
limit of the cable.
In the case of SFrap probe protocols, this indicator gives the input bandwidth used
by the protocol.
Units kilobits per second (Kbps), megabits per second (Mbps), or percentage of total
bandwidth
Default
thresholds
Thresholds will be set only if the interface’s line flow rate has been correctly
captured or entered.
■ WAN interfaces: minimum 60%–maximum 80%
■ LAN interfaces: minimum 30%–maximum 40%
■ ToS roots: minimum 500 Kbps–maximum 2,000 Kbps
■ ToSs: minimum 500 Kbps–maximum 2,000 Kbps
■ VLAN roots: minimum 500 Kbps–maximum 2,000 Kbps
■ VLANs: minimum 500 Kbps–maximum 2,000 Kbps
■ VPN roots: minimum 0–maximum 0
■ VPNs: minimum 0–maximum 0
Points to check saturation rate of an interface varies according to the protocol; for example,
Ethernet saturates at about 40% and X.25 at 80%
