108 Chapter 4: Network Integration and Interception

VLAN ID that is excluded from interception will be bridged without any optimization. This

capability is supported only for tagged VLANs. Trafﬁc received by the inline module on

untagged VLANs will be intercepted and evaluated against the ATP for optimization and

acceleration. By default, TCP trafﬁc received on all VLANs is intercepted and evaluated

against the ATP. VLANs can be excluded or included for interception using the following

commands:

no inline vlan all

inline vlan 100

Example 4-21 shows the resulting InlineGroup conﬁguration.

There are different sequences of the inline CLI command that will result in the same VLAN

ﬁlter being applied. For example,

inline vlan all

no inline vlan 100

results in all VLANs except for 100 being intercepted. But so does the following:

inline vlan native

inline vlan 0-4095

no inline vlan 100-110

inline vlan 101-200

In terms of VLAN assignment, the most permissive command takes precedence. If the

inline group is already conﬁgured with inline vlan all, then you need to selectively remove

VLANs from interception or remove all VLANs and selectively add individual VLANs

back for interception.

When an inline group is in bypass operating mode, a physical cross-connect is enabled

between the two ports in the inline group. This behavior essentially creates a crossover

cable between the two network elements. In cases where the two network elements are

unable to communicate using a crossover cable, line protocol will not be restored when the

inline group is in bypass operating mode. This is generally a nonissue when the switchport

that the LAN InlinePort is connected to supports automatic medium-dependent interface

crossover (MDIX). MDIX allows the switchport to automatically detect the pinouts of the

cables used to connect two devices. In cases where the switchport does not support this

capability, the cabling guidelines outlined in Table 4-4 should be followed.
