  We report on the co-existence of longitudinal and transverse oscillations in
an active filament. On March 15$^{th}$ 2013, a M1.1 class flare was observed in
the active region AR 11692. A CME was found to be associated with the flare.
{The CME generated a shock wave that triggered the oscillations in a nearby
filament}, situated at the south-west of the active region as observed from
National Solar Observatory (NSO)\textit{Global Oscillation Network Group}(GONG)
H$\alpha$ images. In this work we report the longitudinal oscillations in the
two ends of the filament, co-existing with the transverse oscillations. We
propose a scenario in which {an} incoming shock wave hits the filament
obliquely and triggers both longitudinal and transverse oscillations. Using the
observed parameters, we estimate the lower limit of the magnetic field
strength. We use simple pendulum model with gravity as the restoring force to
estimate the radius of curvature. We also calculate the mass accretion rate
which causes the filament motions to damp quite fast.
