What is VSS configuration?
What is VSS configuration?
The Cisco Catalyst 6500 Series Virtual Switching System (VSS) allows the clustering of two chassis together into a single, logical entity. This technology allows for enhancements in all areas of network design, including high availability, scalability, management, and maintenance.
How many Cisco Catalyst 6500 Series switches can be part of a VSS?
two
The Cisco Catalyst 6500 Series Virtual Switching System (VSS) allows the merging of two physical Cisco Catalyst 6500 Series switches together into a single, logically managed entity.
Can I enter into configuration mode of standby switch in VSS?
The command console on the active supervisor engine is used to control both chassis. In virtual switch mode, the command console on the standby supervisor engine blocks attempts to enter configuration mode.
How many switches we can add in VSS?
Comparison Table: Stacking vs VSS
| FEATURE | STACKING | VSS |
|---|---|---|
| Chassis members | Scalable upto 8-9 members | 2 members at max |
| Platform switches | 2960 , 3750 , 3650 , 3850 | 6500 , 6800 , 4500 |
| Control Plane | 1 Control Plane | 1 Control Plane |
| Switch Size | On smaller / Access layer switches | On Core or Aggregation layer switches |
What is VSL in VSS?
A virtual switching system (VSS) contains two chassis that communicate using the virtual switch link (VSL). VSL is a special port group. We recommend that you configure both of the 10-Gigabit Ethernet ports on the supervisor engines as VSL ports.
How many control planes are there in VSS?
1 Control Plane

Is VSS same as Stacking?
A VSS will allow two physical Cisco Catalyst Series Switches to operate as a single logical virtual switch called a virtual switching system….Comparison Table: Stacking vs VSS.
| FEATURE | STACKING | VSS |

What is the difference between Stacking and VSS?
The VSS also simplifies the Layer 3 network topology because the VSS reduces the number of routing peers in the network. Stack Switching: Stack Switching is the concept of stacking the various switching via stack cables so that they can act like a single switch with various ports.
What is LMP & RRP?
LMP verifies link integrity, rejects unidirectional links, and establishes bidirectional communication between switch chassis. 4. LMP exchanges switch IDs in order to detect duplicate IDs. 5. RRP checks hardware versions, software versions, and VSL configurations for compatibility.
What is SSO in VSS?
SSO = Stateful switchover , establish a relation of active / passive between 2 supervisor engines in a chassis to provide uninterrupted L2 functionality in case of a hardware failure.
What is the difference between the Catalyst 6500 series Switch and VSS?
By default, the Catalyst 6500 series switch is configured to operate in standalone mode (the switch is a single chassis). The VSS combines two standalone switches into one virtual switch, operating in virtual switch mode.
What is a VSS in Cisco ASA?
A VSS combines a pair of switches into a single network element. For example, a VSS in the distribution layer of the network interacts with the access and core networks as if it were a single switch. See Figure 4-2. An access switch connects to both chassis of the VSS using one logical port channel.
What is the maximum number of etherchannels a VSS can support?
Note For releases earlier than Cisco IOS Release 12.2 (33)SXI, the maximum number of EtherChannels is 128, allowing 126 user-configurable EtherChannels. Figure 4-4 VSS with MEC The following sections describe the main functionality of a VSS:
Does the VSS support supervisor engine redundancy within a chassis?
• Starting in Cisco IOS Release 12.2 (33)SXI4, the VSS does support supervisor engine redundancy within a chassis. • In releases earlier than Release 12.2 (33) SXH2, the VSS feature and the lawful intercept feature cannot be configured together. ( CSCsl77715) The following sections describe the hardware requirements of a VSS:
